Creating dynamic tooltips on a views toolbar [message #516655]

Hi,

I have a view which contains a table and have declared a menu on the toolbar which allows us to filter the contents of the table. I would like to provide a tooltip on the button generated on the toolbar which describes the current state of the filter but it seems that I am not able to modify the tooltip.

The menu on the toolbar is declared in the plugin.xml as follows

<extension point="org.eclipse.ui.menus">
<menuContribution locationURI="toolbar:com.mycompany.MyView">
<command
commandId="com.mycompany.ui.filters.menu"
icon="icons/filter.gif"
label="Filter Menu"
style="pulldown"
tooltip="Filter Menu"
</command>
</menuContribution>
</extension>

The pull down menu is generated and functions correctly. But it does seem that the tooltip text ('Filter Menu') cannot be changed programatically.

Any help in how to solve this would be appreciated

Thanks
Andy

Hello Andy

I had a similar problem; the only difference with your situation was that my pull-down menu was in the main toolbar not in the view toolbar. I assume that the solution will work also for a view toolbar (not tested this).

My solution was to create a dynamic contribution to the main toolbar and in the code of the dynamic contribution I was able to change the tooltip (actually I changed the image but I could change also the tooltip if I needed to).

I started from this example http://eclipsesource.com/blogs/2009/03/31/replacing-the-pers pective-switcher-in-rcp-apps/ and I needed that my toolbar contribution to be a pull-down menu containing the existing perspectives. When the perspective was changed I needed that image of the icon of the pull-down contribution to be changed to the image of the new perspective. Also another change was to make the menu appear also when the image was clicked (the default implementation is to have the menu appear only when the arrow is clicked).

If you make your handler an IElementUpdater then you can use
org.eclipse.ui.menus.UIElement.setTooltip(String) to change the tooltip.
