I'm working on an Eclipse RCP 4 application and trying to add a HandledToolItem that displays both a label and an image to its left. Problem is whenever i add the image it only displays the image and hides the label. Is there any other way of getting this implemented other than creating a new ToolControl with a Button or a custom Toolbar that can handle this?
It would be nice to have the HandledToolItem because of the simpler management through Commands and Handlers.
Add FORCE_TEXT to the Tags (on the Supplementary tab) for the HandledToolItem in the e4xmi file.

I have implemented Eclipse RCP product in 4.5 (Mars) version. There is a part with toolbar. I want to show the part toolbar always in full span (covering the entire width of the part) and not on the part stack (on right side of the part tab).
I tried to add Part-Toolbar-FullSpan tag to the Part and also to the part toolbar but it is not helping.
I also tried to create a custom toolbar but that approach did not work out.
Do you know how I can show the part toolbar in full span?
Thank you.
Part-Toolbar-FullSpan appears to be for the e(fx)clipse JavaFX stack renderer only so it won't work with SWT.
The SWT stack renderer org.eclipse.e4.ui.workbench.renderers.swt.StackRenderer uses the setTopRight method of CTabFolder to manage the toolbar. This will only push the toolbar on to a separate row when there not enough space for it on the tab row.
So it looks like the only way to do this would be to define a custom renderer factory and override the stack renderer. Unfortunately for what you want this would be a substantial change to the renderer.
I am trying to customize PartStack header of a view in rcp application. My goal is to customize the coloring of the header and to add date and time to it and hide minimize and maximize buttons. Buttons can be hidden using css but other goals give me hard time. At the moment I am looking to use a custom renderer by overriding some methods in StackRenderer class. Is that a right approach or is there another renderer that I shoud use?
If you don't want the min/max buttons then do not include MinMaxAddon in the Add On list in the Application.e4xmi.
Using a custom renderer for StackRenderer is useful for changing the text of the part tabs items. If you want to put text elsewhere on the part stack line you will probably need to look at the MinMaxAddon to see how it does that.
The JavaFX 2 colour picker has a button that pops up a colour chooser pane like so:
I'd like to do something similar, in that I'd like a custom pane to pop up when the button is clicked on and disappear when something else is clicked (in my case, a few image thumbnails). What would be the best way of achieving this? Should I use a ContextMenu and add a pane to a MenuItem somehow, or is there something else I should look at?
It's kind of difficult to do well with the current JavaFX 2.2 API.
Here are some options.
Use a MenuButton with a graphic set in it's MenuItem
This is the approach taken in Button with popup showed below's executable sample code.
Use a PopupControl
Take a look at how the ColorPicker does this in it's code.
ColorPicker extends PopupControl. You could do this, but not all of the API required to build your own PopupControl is currently public. So, for JavaFX 2.2, you would have to rely on internal com.sun classes which are deprecated and will be replaced by public javafx.scene.control classes in JDK8.
Use a ContextMenu
So, I think your idea to "use a ContextMenu and add a pane to a MenuItem" is probably the best approach for now. You should be able to do this by using a CustomMenuItem or setting a graphic on a normal MenuItem. The ContextMenu has nice relative positioning logic. A ContextMenu can also be triggered by a MenuButton.
Use a Custom Dialog
To do this, display a transparent stage at a location relative to the node.
There is some sample code to get you started which I have temporarily linked here.
The sample code does relative positioning to the sides of the main window, but you could update it to perform positioning relative to the sides of a given node (like the ContextMenu's show method).
Use a Glass Pane
To do this, create a StackPane as your root of your main window. Place your main content pane as the first node in the StackPane and then create a Group as the second node in the stackpane, so that it will layer over the top of the main content. Normally, the top group contains nothing, but when you want to show your popup, place it in the top group and translate it to a location relative to the appropriate node in your main content.
You could look at how the anchor nodes in this demo are used to see how this might be adaptable to your context.
Is there a relevant update for this for JavaFX8?
There is not much difference of relevance for Java 8, in general the options are as outlined in this post based on Java 2.2 functionality. Java 8 does add Dialog and Alert functionality, but those are more targeted at use of dialogs with borders, titles and buttons rather than the kind of functionality desired in the question. Perhaps you might be able to start from the Dialog class and heavily customize it to get something close to what is needed, but you are probably better off starting from a blank stage or PopupControl instead.
Chat portlet is displayed as a long bar at the bottom of the screen. I want to write a similiar portlet.
I can draw my bar anyway on the screen with CSS styles and also I have learned how to make static portlet visible always for all users with portal-ext.propeties.
But along with my bar, Liferay draws standard portlet frame with a title and controls on it. I found that it is named "topper" in HTML code.
So how to disable topper and border for one specific portlet in the way chat-portlet did it? I failed to figure this out from chat-portlet sources.
I found two options which can be relevant to this
<use-default-template>false</use-default-template>
<system>true</system>
but they weren't work.
First one causes ClassNotFoundException and second one causes portlet content not reaching page source.
Thanks.
I was to use
<use-default-template>false</use-default-template>
correctly. It does not work if placed in incorrect order.
I'm trying to build a similar menu like in http://www.gwt-ext.com/demo/#menuButton. But i am using the SmartGWT instead of GWT-Ext and GWT Designer in Eclipse. I have built the SectionStack and add to it 3 sections. My problem is that i do not know what components to add in each section to get the selected items as in the example 'Showcase Explorer' menu of the link. Like the example i want to fill each section with several text lines but if i add just Label components then there are not selectable like in the example (when you view the menu in accordion mode).
Why dont you use http://www.smartclient.com/smartgwt/showcase/#menus_category_treebinding this menu instead?
