add combobox to toolbar and change drop-down list programmatically [message #648194]

Hi,

I am trying to add a combobox to a toolbar in an eclipse rcp app. but I'd also like to have the content of the drop-down list changing programmatically (i.e. depending on other events). Right now this combobox works, but it's on a view instead of a toolbar.

Is there a way to achieve this by setting the plugin.xml (it looks like the content of the dropdown needs to be set this way at the beginning, and cannot be changed programmatically)?
Is there another way to do that?

Thanks,
Francesca

I found out how to do this, so I thought I may as well share.

To show a combobox (or other buttons) on the toolbar one can create a class for example

public class DoThis extends Action implements IWorkbenchAction {
public DoThis() {

}

|

this class should implements the method

public Menu getMenu(Control parent) {

}
to actually show a combobox and the menu should be populated by menuitems.

After that one needs to add this action to the toolbar. To do that I have written this code in the class that display the view that contains the toolbar

DoThis myaction = new DoThis();
getViewSite().getActionBArs().getToolBarManager().add(myacti on);

You can place a <control/> in a toolbar using the org.eclipse.ui.menus
contribution. You can also create a dropdown toolitem and fill in the
dropdown menu dynamically also use org.eclipse.ui.menus and a <dynamic/>
element.

See some of the examples in my .sig links
