Different "backgroundColor" for ToolTip's in Flex.

kumargandhi — Tue, 07 Oct 2008 16:18:36 +0000

Few days back one of the reader commented whether there is a way to change the "backgroundColor" of the ToolTips for different Controls dynamically in Flex. And my answer was "yes" and solution is here in this post.

What we got to do to achieve this ??

First we got to know about the Class StyleManager.

Basic information About the Class.

The StyleManager class lets you access class selectors and type selectors in ActionScript. It also lets you apply inheritable and noninheritable properties globally. Using the StyleManager, you can define new CSS style declarations and apply them to controls in your Flex applications.

[ These lines are from the HELP in Flex builder as they are the BEST, for any further information refer HELP from Flex Builder. :-) ]

Then Setting Styles with the StyleManager.

To set a value using the StyleManager, use the following syntax:

mx.styles.StyleManager.getStyleDeclaration(style_name).

setStyle("property", value);

Example ::

For Example here i want the backgroundColor of the ToolTip to change dynamically. So the line of code would be like below.

StyleManager.getStyleDeclaration("ToolTip").

setStyle("backgroundColor","red");

This can be called at any point where you would prefer to change , for example i can call this line on rollOver of a Button or a Control.[ Just keep in mind that this will reflect all the Visible controls in the App so care should be taken to reset the defaults when necessary ]

Now Enjoy this Demo here.

Comments are welcome. :-) , Enjoy the Post.

tooltips with jquery 2: jHelperTip

santiagogl — Mon, 06 Oct 2008 03:20:04 +0000

jHelperTip worked perfectly for what i was trying to do. it has a demo page.

Different positioning for different tooltips using ToolTip Manager Class.

kumargandhi — Sat, 13 Sep 2008 04:35:30 +0000

my previous post tells the basic usage of the ToolTip Manager Class , here i am with an example where in you can give different positioning for different tooltips.This means if i have two controls and for the first control i want the tooltip on right and for the second control i want the tooltip on bottom of the control, so this can be achived using the ToolTip Manager class and iam going to tell you how that can be achived.

Here we got to use the method called createToolTip(), which takes the parameters.

syntax ::

createToolTip(text:String, x:Number, y:Number, errorTipBorderStyle:String,
context:IUIComponent):IToolTip

Here we will be usign the text,x,y parameters specifications only for our positioning.

First create an instance to the ToolTip Class and call the createToolTip method of the ToolTip Manager and asing the return value to the ToolTip Class instance.Like below.

private var tip:ToolTip;

tip = ToolTipManager.createToolTip('Right side tooltip',
event.currentTarget.x + event.currentTarget.width + 10,
event.currentTarget.y)
as ToolTip;

Call these staments on an event of the control for exmaple on mouseOver and we got to destroy the ToolTip instance after the usage like on mouseOut.So that the instance can be used for other control in the Application.

And to destroy the ToolTip instance use the method destroyToolTip(tip) of the ToolTip Manager Class.

Similarly we can write code for any positioning of the tooltip for any control.

Enjoy the post and tune on to see the source code for this Exmaple.

Anteprima delle immagini in un tooltip

fedeweb — Thu, 11 Sep 2008 08:04:22 +0000

Tempo fa avevo scritto un articolo su come creare dei tooltip gradevoli, grazie a javascript.

Oggi vedremo come ottenere lo stesso effetto con le immagini, cioè al passaggio del mouse sulle miniature compariranno le anteprime, con la didascalia, il tutto sfruttando la libreria jquery.

Per capire meglio di cosa si tratta guardate l'esempio.

Prima di cominciare a seguire la spiegazione scaricate i file necessari.

Vediamo come ottenere questo effetto, qui di seguito:

1) tra i tag <head> e </head> inserite queste righe di codice

2) Per le miniature dovete scrivere questo codice; in questo primo esempio la didascalia non compare.

<a href="1.jpg" class="preview"><img src="1s.jpg" alt="gallery thumbnail" /></a>

Se invece volete aggiungere anche la didascalia dovete aggiungere il tag title:

<a href="image.jpg" class="preview" title="Great looking landscape">Roll over to preview</a>

Nella fonte da cui ho preso le informazioni sono presenti altri due esempi per sfruttare i tooltip in modi diversi da quelli proposti nell'articolo.

Show div as tooltip using javascript

sujitkumar21 — Fri, 05 Sep 2008 04:30:16 +0000

function mouseXY(e)
{
var posx = 0;
var posy = 0;
if (e.pageX || e.pageY)
{
posx = e.pageX+5;
posy = e.pageY;
}
else if (e.clientX || e.clientY)
{
posx = e.clientX+5;
posy = e.clientY;
}

document.getElementById("movingDiv").style.right=posy+"px";
document.getElementById("movingDiv").style.left=posx+"px";
document.getElementById("movingDiv").style.top=posy+"px";
document.getElementById("movingDiv").style.display='block';
}

function hideDiv()
{
document.getElementById("movingDiv").style.display='none';
}

window.onload=mouseXY;

here "movingDiv" is div.

CSS-Tooltips erstellen: Infoboxen über HTML-Elementen / Teil 1

sura1 — Thu, 24 Jul 2008 18:52:15 +0000

CSS - T o o l t i p :

Ein Tooltip (auch »Quickinfo«, »Kurzinfo«; sinngemäß übersetzt: Hilfe zu einem Werkzeug) ist ein kleines Fenster in einer grafischen Benutzeroberfläche, das dem Benutzer weitere Informationen zu einem Objekt anzeigt.

Es wird zum Beispiel in Browsern zur Beschreibung von Links oder zur Erklärung von Icons, d.h. Symbolen oder Bildchen in Computerprogrammen, verwendet und erscheint, wenn der Mauszeiger über das entsprechende Objekt fährt oder eine gewisse Zeit über dem Objekt verbleibt.

Tooltips sind somit nichts anderes als kleine Informationsboxen über HTML-Elementen. Sie stellen aber auch ein Steuerelement dar, das ein Popupfenster erstellt, in dem Informationen für ein Element in der Oberfläche angezeigt werden.

Ich habe mich im Web nach Tooltips umgesehen, die nur mit Hilfe von HTML und CSS errichtet werden können.

Wichtig (!!):

Sie sollten sich in CSS und HTML gut auskennen, um die Beispiele verstehen und bearbeiten zu können; das Stylesheet der jeweilige html-Datei finden Sie im head-Bereich!

Es gibt eine unübersichtliche Fülle, welche mit reinem CSS erstellt wurden - ich habe zur Einleitung 6 einfache Beispiele ausgewählt. Dazu muß gesagt werden, dass ich bei einigen Tooltips das Stylesheet unverändert gelassen habe; bei den anderen wurde z.B. die Hintergrundfarbe geändert, der margin (Außenabstand) bzw. der Innenabstand (padding) angepasst etc.

Beispiel 1:

Auf der Webseite von http://www.kollermedia.at/archive/2008/03/24/easy-css-tooltip/ habe ich den ersten CSS-Tooltip gefunden. Das Script ist kleiner als 1KB und besteht aus 1 html-Zeile und 3 Zeilen CSS. Deshalb wird es von Herrn Jürgen Koller "easy-css-tooltip" genannt - was auch tatsächlich zutrifft.

Klicken Sie auf den Screenshot oder sehen Sie hier: Easy CSS Tooltip - by Kollermedia.at

Beispiel 2:

Basierend auf dem ersten Beispiel habe ich den HTML-Quelltext ein wenig verändert; der Tooltip befindet sich hier mitten im Blindtext, welchen ich in einen Link über meine Blogseite eingebaut habe.

Klicken Sie auf den Screenshot oder sehen sie hier: Variante zu Kollermedia.at

Beispiel 3:

Wenn Sie mit der Maus über den gelben Textbereich fahren, erscheint ein CSS-Infofenster und die Hintergrundfarbe im Text ändert seine Farbe.

Good User Interface Design Tips

ralikalyani — Wed, 16 Jul 2008 18:57:34 +0000

General application user interface guidelines :

Always use cute icons, buttons, and graphics. Everyone loves big red hearts, pink bunnies, and yellow smily faces.

Don't be afraid to experiment with colors!

Your application should play fun sounds while operating to keep the users entertained.

Never, ever, under any circumstance use the OS-native graphical controls or widgets. Users get bored of the same old buttons, text boxes, and stuff.

When possible, disable window management and use unusual, oddly placed graphics for the windowing functions such as the window close option.

When writing your own controls or widgets, make absolutely sure they look and feel nothing like the OS-native widgets or anything else the user might expect. Otherwise you might accidentally make the user think that your application is actually designed for their OS.

Use your own creative ideas on how a "save as" dialog should look and work. Built in ones are always too limiting.

It is important that the user should never be able to tell the difference between a checked and unchecked check box or option box.

Always use obscure or poorly drawn graphics for your tool bar buttons, and never put text on them.

Avoid including a preferences or options dialog. Instead, let the user use the standard OS provided text editor or an editor of their choosing to edit text configuration files. .

Users need time to think about what they are doing and get coffee. Your application should always take at least 5 minutes to load even on the fastest available computer.

Make sure an accidental double-click on a single-click item does something really nasty or unexpected.

Tool tips are the perfect way to display critical information.

To get the most screen space, force your application to always run maximized.

Always make the default positions of floating properties windows cover something important.

Use the most exotic fonts you can find.

Your application's user interface should be flexible and customizable to the point where if the user accidentally sneezes on the mouse or keyboard they will have to spend the next half an hour setting things back.

Let a 5-year old draw your graphics, including your corporate logo.

File browsing dialogs are not needed, users can easily remember and type in long file paths.

Design your application so it requires the user to set their tiny monitor to 10512*7430.

Always crash at a critical step and then display a fake apology to the user.

It is a mistake to make use of application hooks in the native desktop environment such as new file templates, file associations, or program menu icons.

The exception to the above is placing icons in the system tray. Place as many icons as you can in the system tray and make sure that the user can not remove them.

If your program implements keyboard shortcuts be original and make them completely different from any other applications.

Rent extra UI space in your application out for advertising. Advertising benefits the users and your wallet.

Never underestimate the power of nudity.

Don't forget to embed a hidden video game as an "easter egg".

Application Help: How to make a help system that is impervious to usefulness.

There is no need to include a manual with software. These days users are smart enough to figure out this kind of thing on their own.

If you do include documentation, there is no need for printed manuals. Users love staring in to a 17 inch light bulb all day.

Always put your installation instructions on the CD-rom rather than in a printed manual to save paper. The instructions should be installed with the rest of the program so they are not accessible until it is installed.

Keep help files simple. Only state the bleeding obvious about any given topic.

There is no need to use consistent terminology.

For program error, warning, question, and information messages, explain what is going on to the user in the most technical terms. They really need to know and learn this stuff because it is important. As part of the message dialog include a help button that opens the help file and displays exactly what the message just said.

Display as many information and question messages as possible in as many different places as possible. Except before critical irreversible operations such as wiping the hard drive.

It is acceptable to use "Engrish" throughout your application. All your help file are belong to us.

Making the web do things it has never done before

(and should never do again).

Always build a web browser in to your application. For best results make your own web browser.

Always hard code hyperlinks in to your application. Then make sure that the links don't work two months after the application is deployed.

When you launch a web browser, never use the user's default browser. Always launch the crappiest one available (I.E.: IE) (See above, you should write your own).

Always use hyperlinks instead of buttons. Hyperlinks are cool.

Be sure to include a throbber graphic in every window of your application.

Applications should look like web pages because the web is the embodiment of usability.

All modern applications are required to automatically sign users up for spam.

OS Specific tips

For a great first impression during your OS setup, never set the video to a refresh rate that works with user's monitor.

In fact, your OS should never, ever set the proper refresh rate for the monitor. Eye strain is good. In fact, whenever possible set it to a refresh rate that the monitor can't handle at all. If the user does manage to set a higher refresh rate, make sure it is non-standard so they have to fiddle with the monitor sizing and positioning. Bonus points for finding a refresh rate that makes the monitor blow up.

When packaging a GUI or operating system make sure the same functionality is available in at least a dozen different places in unrelated programs.

Include three of every kind of application program. (four or more if possible).

Install all possible advanced utilities and mindless junk that the typical user will never use.

Uninstallation options are out of style, don't include any. If you do need to include them make sure they always choke on dependencies.

It doesn't matter if your file manager / desktop shell is slow and sluggish. Go ahead and integrate it with your web browser. In fact, integrate it with several web browses while you are at it.

Application design for the ultimate user experience (in hell)

Begin coding the guts of the program immediately. Designing the UI can come later in the development process.

Don't waste time writing efficient code. GUIs don't need to be responsive and it is easy to make users upgrade to the latest 10,000,000 terahertz CPU and who doesn't need another zillion gigabytes of ram?

You can implement features half way. Your users will forgive you. (And if they don't, screw them anyway). Or you can always make them upgrade to the next version.

You don't even need to finish your software, if someone else has a problem with it they can fix it themselves.

It is safe to ignore the overall purpose of the application you are writing. Just make it do what you want.

There is no need to do any kind of user testing or research. Programmers always know the best way to design a user interface.

Let the users dictate design and implementation decisions, after all they know what they need.

If this is a corporate environment, always design the user interface the way the boss wants it. After all, that degree in user interface design he has is how he got to be the boss right?

When porting your application to another OS platform, there is no need at all to modify the way your application looks or behaves.

Always hard code all references to the file path your application must run in. The user will never have a need to install anywhere else and you will never run in to naming conflicts.

Sue anyone who makes a UI even remotely like yours. That's what the legal system is there for right?

Always use bizarre, scary sounding code names for the name of your application. For best results it should be an acronym for something that doesn't make any sense, and the acronym should be recursive.

Never remove old, obsolete, buggy, or nonsensical features from your application.

Pre-load your (now huge) application at system startup. It doesn't matter if it slows down the rest of the system, it is important that your application, which most users only use only occasionally, start the fastest. .

Add all possible features to your application. Even those that already exist in the OS. In fact, your application should eventually become an OS.

Prototype & JavaScript based tooltip

ibnaziz — Thu, 15 May 2008 10:00:37 +0000

Context :

Standard tooltips can be created using the 'title' attribute of the html tags, but these are not configurable and the layout may vary depending on your browser. Also, at times, the need may arise to have more than just one line of text showing in the tooltip.

Solution :

To make use of a tiny javascript library based on the prototype.js that allows multi-line formatted tooltips to popup, when the cursor moves over the target element. The following four steps are required...

Step 1: Include the appropriate javascript libraries...

<script src="/javascripts/prototype-1.6.0.2.js" type="text/javascript"/>
<script src="/javascripts/tooltip-v0.1.js" type="text/javascript"/>

Step 2: Define the tooltip 'div' tag and give it a unique id. It may be formatted like any other html element...

<div id='tooltip_unique_id'
     style="display:none; margin: 5px; background-color: red">
    Tooltip content line 1 <br/>
    <b>Tooltip content line 2</b>
</div>

Step 3: Determine the target element, upon which if the mouse moves over, the tooltip is shown. Do this by giving it a unque id.

    <img id="target_unique_id" src="..." />

Step 4: Invoke the javascript 'Tooltip' constructor, informing it of the unique tooltip and target element id's defined earlier on...

<script type="text/javascript">
    new Tooltip('tooltip_unique_id', 'target_unique_id');
</script>

... and that's all there is to it !

How to enable tooltip for your dialog controls?

Jijo.Raj — Mon, 28 Apr 2008 17:44:44 +0000

Have a number of controls in your dialog. May be a single line of tooltip will add beauty to it. So how can you add tooltips for the controls in your dialog? Its easy. Just follow the steps.

Basically you've to enable tooltips by calling EnableToolTips() and then handle the TTN_NEEDTEXT message in your dialog. When its time to show a tooltip, windows will send you the TTN_NEEDTEXT message with control' handle and you've to specify the tooltip text to be shown. From handle you can get Dialog control ID. Once you have the control ID, you can specify which tooltip have to be shown for that control. See it step by step. I assume you use MFC. Eventhough you follow the tradition style, just go through the steps, you can easily grasp it.

1) Call EnableToolTips() in yout dialog initialize function. The best place is in dialog initialization routine - CDialog::OnInitDialog().
2) Now add message handler for TTN_NEEDTEXT in messagemap. The following codesnippet enables tooltip notification for all controls in your dialog.

BEGIN_MESSAGE_MAP(CDialogDlg, CDialog)
    ...
    ON_NOTIFY_EX_RANGE(TTN_NEEDTEXT, 0, 0xFFFF, OnToolTipNotify)
END_MESSAGE_MAP()

3) Now declare the tooltip handler in your header as follows.

afx_msg BOOL OnToolTipNotify( UINT id,
                              NMHDR* pNMHDR,
                              LRESULT* pResult );

4) Now define the tooltip handler in your cpp file as follows

BOOL CDialogDlg::OnToolTipNotify( UINT id,
                                  NMHDR * pNMHDR,
                                  LRESULT * pResult )
{
    // Get the tooltip structure.
    TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR;

    // Actually the idFrom holds Control's handle.
    UINT CtrlHandle = pNMHDR->idFrom;

    // Check once again that the idFrom holds handle itself.
    if (pTTT->uFlags & TTF_IDISHWND)
    {
        // Get the control's ID.
        UINT nID = ::GetDlgCtrlID( HWND( CtrlHandle ));

        // Now you have the ID. depends on control,
        // set your tooltip message.
        switch( nID )
        {
        case IDC_BUTTON1:
                // Set the tooltip text.
                pTTT->lpszText = _T("First Button");
            break;

        case IDC_BUTTON2:
            // Set the tooltip text.
            pTTT->lpszText = _T("Second Button");
            break;

        default:
            // Set the tooltip text.
            pTTT->lpszText = _T("Tooltips everywhere!!!");
            break;
        }

        return TRUE;
    }

    // Not handled.
    return FALSE;
}

DataGridRow and Tooltip

lee — Mon, 21 Apr 2008 12:57:00 +0000

We can use Popup to display a tooltip at the row level in the datagrid

Here is sample code

<UserControl x:Class="slapp1a.Page"
    xmlns="http://schemas.microsoft.com/client/2007“
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml“
             xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data"
             Width="600″ Height="600″>
    <UserControl.Resources>
        <DataTemplate x:Key="dt">
            <StackPanel Orientation="Horizontal">
            <TextBlock Text="This is a tooltip for the Row with content : “></TextBlock>
                <TextBlock Text="{Binding}"></TextBlock>
            </StackPanel>
        </DataTemplate>
    </UserControl.Resources>
    <Grid x:Name="LayoutRoot" Background="White">
        <data:DataGrid x:Name="dataGrid1″
                       Height="400″
                       Width="450″
                       Margin="0,5,0,10″
                       AutoGenerateColumns="True" />
        <Popup x:Name="myPopup">
            <ContentControl x:Name="PopupContent" ContentTemplate="{StaticResource dt}"></ContentControl>
        </Popup>
    </Grid>
</UserControl>
and in codebehind. all we are doing is handling the PreparingRow event to attach evenhandlers for MouseEvents, where we position the popup and set the content for the contentcontrol in the popup.

Did not try it, but we could change it use storyboards to introduce some delay before showing the tooltip and ofcourse customize the appearance

public partial class Page : UserControl
    {
        public Page()
        {
            InitializeComponent();
            dataGrid1.ItemsSource = new string[] { "data 1", "data 2" };
            dataGrid1.PreparingRow += new EventHandler<DataGridRowEventArgs>(dataGrid1_PreparingRow);
        }        void dataGrid1_PreparingRow(object sender, DataGridRowEventArgs e)
        {
            e.Row.MouseEnter += new MouseEventHandler(Row_MouseEnter);
            e.Row.MouseLeave += new MouseEventHandler(Row_MouseLeave);
        }

        void Row_MouseLeave(object sender, MouseEventArgs e)
        {
            myPopup.IsOpen = false;
        }

        void Row_MouseEnter(object sender, MouseEventArgs e)
        {
            PopupContent.Content = (sender as DataGridRow).DataContext;
            Point p = e.GetPosition(null);
            myPopup.HorizontalOffset = p.X;
            myPopup.VerticalOffset = p.Y;
            myPopup.IsOpen = true;
        }

    }

Combo Box Tooltip and Icons example

equilibrismi — Wed, 02 Jul 2008 19:28:32 +0000

Here we have an easy example of customizing values into a combo box.

Values intend to display names and status of friends.

Starting from a nice example from flexexamples.com, i compare some other different ways to display data and icons.

Ecco un piccolissimo esempio di come si possono customizzare i dati visualizzati in un combo box tramite tooltip e tramite immagini.

Sono partito da un esempio di flexexamples.com per provare diversi modi e diverse funzionalità.
