Is there a way to add text next to the action icon in the toolbar of an eclipse RCP UI Form? If you do not assign the Action an ImageDescriptor, the action will be displayed containing only text. If you do give it an ImageDescriptor, it displays only the image. I want to display both side by side, within one button - is there a way to do this?
This will have only the text "Description" in the button on the toolbar:
myAction = new Action("Description", SWT.PUSH) {
#Override
public void run() {}
};
myForm.getToolBarManager().add(myAction);
But adding an image will cause the the text to be replaced:
myAction.setImageDescriptor(newImage);
I was eventually able to find an answer to my issue, hopefully it's helpful to anyone else who runs into this problem. I found this in the Eclipse Rich Client Platform (2nd Ed.) book.
The Action must be converted to an ActionContributionItem with its mode set to MODE_FORCE_TEXT. This will display both the text and the image in the toolbar.
ActionContributionItem aCI = new ActionContributionItem(myAction);
aCI.setMode(ActionContributionItem.MODE_FORCE_TEXT);
myForm.getToolBarManager().add(aCI);

I am currently working on a web browser application using Eclipse e4.
I want to put on the toolbar a toggle button for saving my favorites url's.
I want it to be like in Google Chrome , a star which gets the yellow color when it's pressed(the link was added to favorites).
How can I do this?
Should I use for this the Application.e4xmi ?
You can use the Application.e4xmi if this is a tool bar for a Window or a Part. You would use a 'Handled Tool Item' in the tool bar.
The Application.e4xmi does not provide a way to set separate icons for the selected and normal states of a tool item so you will have to do this in the handler class. Something like:
#Execute
public void execute(MToolItem mitem)
{
if (mitem.isSelected())
mitem.setIconURI("platform:/plugin/your.plugin.id/icons/selectedimage.png");
else
mitem.setIconURI("platform:/plugin/your.plugin.id/icons/unselectedimage.png");
// TODO other code
}
I wanted to migrate my existing add-on for firefox and chrome to crossrider in order to have it also with safari and IE, but i've a few doubts that mayble Schlomo (or any Crossrider developercan) can help me to solve them.
Questions :
Can i add a popup pane when someone clicks on the add-on button showing some kind of options inside it?
Can i add a blinking icon to the actual icon showing some kind of event happened like incoming chat or so?
Is there a way to add the red text box like in chrome showing at the bottom right of the icon some kind of text?
Thanks a lot!
When you pose the question like that, I can only hope the following answers will serve to allay your doubts and enlighten :)
First off, I would recommend familiarizing yourself with How to add a browser button to your Crossrider extension in general and the button popup feature specifically.
In answer to your specific questions:
You can use the button popup feature and build the required options in there. Take a look at the Button Popup Menu demo extension to get you started.
Whilst you can't make the button blink, you can alternate the button icon to make it look like blinking (see example).
In short, yes. Simply use the appAPI.browserAction.setBadgeText and appAPI.browserAction.setBadgeBackgroundColor methods (see example).
The following example bring together the key elements in the background.js code required to achieve the solutions mentioned. Look at the popup.html file in the Button Popup Menu for an example of how to build the options page.
appAPI.ready(function() {
var sid, // Blink interval id
alt=0, // Blink alternation state
icon = { // Blink icons
0: 'icons/icon0.png',
1: 'icons/icon1.png'
};
// Set the initial icon for the button
appAPI.browserAction.setResourceIcon(icon[0]);
// Sets the popup for the button
appAPI.browserAction.setPopup({
resourcePath:'html/popup.html',
height: 300,
width: 300
});
if (true) { // blink condition, set to true for this example
// Blink icon
sid = appAPI.setInterval(function() {
alt = 1 - alt;
appAPI.browserAction.setResourceIcon(icon[alt]);
}, 1 * 1000);
} else {
appAPI.clearInterval(sid);
}
if (true) { // show button text condition, set to true for this example
// Add red text box to icon
appAPI.browserAction.setBadgeText('ext', [255,0,0,255]);
}
});

I'm trying to create a GWT button that includes both an image and text like this:
I can create and set the button image like this:
PushButton button = new PushButton();
button.getUpFace().setImage(new Image(icon));
but if I do this the image disappears:
button.setText("ABC");
How can I keep both? I would prefer not to use the setHtml method because that would create a new HTTP request
EDIT: The problem with calling setHTML() is that it causes the browser to send another HTTP request to the server. This means that when I change the icon the button is blank for a second or two while the browser waits for a response from the server - obviously this not ideal. I'm looking for a way to use the image that is in memory in the form of a ImageResource object. Thanks!
There are lots of ways to achieve this.
Please have a look at below post asked in the same context:
HTML/CSS - Adding an Icon to a button
Adding icons to an button in gwt
GWT Custom Button with Icon above Text
Sample code:
Button button = new Button();
// get image form CSS resource
String url = new Image(Resources.INSTANCE.cut()).getUrl();
// get image from url
String url = "https://cdn3.iconfinder.com/data/icons/tango-icon-library/48/edit-cut-64.png";
// get image from the project war/images folder
String url = GWT.getHostPageBaseURL() + "images/cut.png";
String html = "<div><center><img src = '" + url
+ "'></img></center><label>Cut</label></br></div>";
button.setHTML(html);
Note: you can move it to CSS as well and append in HTML.
___________-
EDIT
You can achieve it using PushButton as well using setInnerHTML()method that will benefit from ImageResource as well.
final PushButton pushButton = new PushButton(new Image(Resources.INSTANCE.old_cut_icon()));
pushButton.getElement().setInnerHTML("<div><center>"+pushButton.getElement().getInnerHTML()+"</center><label><center>Cut</center></label></div>");
now simply call setImage() whenever needed to change the icon only.
pushButton.getUpFace().setImage(new Image(Resources.INSTANCE.new_cut_icon()));
Screenshot
Set a text on your button. Also set a CSS style:
.myButton {
background-image:url('/images/icon/cut.png');
background-position:center top;
padding: 28px 2px 2px;
}
Adjust padding depending on the size of your image.
An alternative approach is to create a widget that combines a button with a label, and either (1) put them in a LayoutPanel, specifying the position that you want, or (2) use CSS to move the label on top of the button (better).
I have a ListView that displays a list of Panels, one below the other. Every panel features a button (implemented via AjaxLink) that closes the panel and removes it from the list.
This is how the ListView is initalized and how the panels are created:
panelsList = new ArrayList<MyPanel>();
pnlContainer = new WebMarkupContainer("pnlContainer");
ListView<MyPanel> pnlItems = new ListView<MyPanel>("pnlItems", panelsList) {
#Override
protected void populateItem(final ListItem<MyPanel> item) {
item.add(item.getModelObject());
item.add(new AjaxLink<Void>("pnlClose") {
#Override
public void onClick(AjaxRequestTarget target) {
panelsList.remove(item.getModelObject());
target.add(pnlContainer); // repaint panel container
}
});
}
};
pnlContainer.setOutputMarkupId(true);
pnlContainer.add(pnlItems);
add(pnlContainer);
This works so far - the actions that trigger adding new panels (usually also AjaxLinks) do what they should and the new panel is added and displayed correctly. But I have problems getting the close button to fully work.
Please see the following steps:
1) I start the server and navigate to the main page. The ListView is initially populated with one panel.
Close-button-code of this panel:
<a wicket:id="pnlClose" id="pnlClose7" href="javascript:;">Close</a>
Searching the page code for pnlClose7 finds the following javascript code that makes the button work as expected:
Wicket.Ajax.ajax({"u":"./?0-1.IBehaviorListener.0-pnlContainer-pnlItems-0-pnlClose","e":"click","c":"pnlClose7"});;
Note: I do not press the button now, if i would, it would work as expected (thoroughly tested).
2) I trigger an action that opens a second panel. The panel is displayed below the first one as expected.
Close-button of the first panel:
<a wicket:id="pnlClose" id="pnlClosef" href="javascript:;">X</i></a>
Close-button of the second panel:
<a wicket:id="pnlClose" id="pnlClose10" href="javascript:;">X</i></a>
But now, neither searching for pnlClosef nor pnlClose10 finds some javascript code. The buttons (both!) do not work. I can still find the javascript code for pnlClose7.
3) I reload the page via pressing F5.
The button IDs change to pnlClose1a and pnlClose1b. Both IDs have javascript counterparts and work.
4) I press the first button (upper panel, ID pnlClose1a). The panel is closed as expected.
The remaining button's ID changes to pnlClose1c, again without a javascript counterpart. Javascript code for pnlClose1a and pnlClose1b is still present.
To make a long story short, the javascript handlers for my AjaxLinks seem to have shyness issues and only appear after I press F5 or reload the whole page in any other manner. I guess thats because repainting the pnlContainer changes the IDs of the current panels - but why is the linked javascript not updated at the same time? Is there anything I can change in my code to update the whole page without completely reloading it?
Wierd thing is that I am pretty sure this worked before... But I checked the whole class history and can't find any major change that would have triggered that. The ListView-code is mainly static since I added it.
I was had similiar problem. if you have any hardcoded javascript code in your page or panels html file (using <script> tag) remove it and set that js code in renderHead of your panel.
private ImgButton button = new ImgButton();
...
button.setSrc("iconName.jpg");
GWT or SmartGWT, I cannot tell exactly, generate state word to concatene it on the name of file.
Example to clarify :
On focus, iconName.jpg become iconName_Focus.jpg
On mouse down click, iconName.jpg become iconName_Down.jpg
On over, iconName.jpg become iconName_Over.jpg
Because these images are custom images, I want to tell GWT to take a default image when I didn't provide the corresponding image.
For example, when over event is fire and iconName_Over.jpg does not exist then use iconName.jpg.
Use the setShow{State} or setShow{State}Icon methods accordingly. For example for disabling the mouse down state, use setShowDown(Boolean.FALSE). For not showing a different icon when the mouse goes down on the button, use the setShowDownIcon(Boolean.FALSE). The rest of the actions have accordingly named methods you can look up at the ImgButton's javadoc page.
