toolbar doesn't wrap [message #916084]

Hi,

although I created a ToolBarManager with the SWT.WRAP option it doesn't
wrap when resizing the view containing the controlArea composite to a
width too small to display all toolbar items in a single row. This is
the code that creates the ToolbarManager and adds items to it:

protected void buildControlArea(Composite controlArea) {
ToolBarManager toolBarManager = new
ToolBarManager(SWT.HORIZONTAL|SWT.FLAT|SWT.WRAP);
toolBarManager.createControl(controlArea);

for (IContributionItem contribution : _controlAreaContributions) {
toolBarManager.add(contribution);
}

toolBarManager.update(true);
}

Does anybody have an idea why wrapping doesn't work?

Do I have to register an eventhandler with some kind of resize event or
do I have to take special care which layout mangersto use for the tool
bar's parent composite?

Would be great if anybody could help!

Regards,
Dirk

I don't think the toolbar will be called to layout unless it's parent explicitly told it to do so.

I'm sure you could go the brute force way and add a control listener and manually calling layout on the toolbar when the surrounding control has been resized.

How do you have the parent layed out? I'll experiment with it tonight and get back to you.
