SWTBotTreeItem.getTooltipText [message #1756064]

Have you tried getTooltipText for SWTBotTreeItem or SWTBotTableItem?
It returns "" for me. I looked into the code. I thought that it would return "" for any TreeItem, TableItem and similar objects that occur within specific controls.

SWT's TreeItem has swt.widgets.Widget as baseclass which does not provide getToolTipText() method. So AbstractSWTBot.getToolTipText() when calls ReflectionInvoker's run() method for TreeItem, it throws NoSuchMethodException and hence returns "".

The application can use jface's CellLabelProvider to provide tooltip. It may not be possible for swtbot to access those things but returning "" also can mislead.
Am I correct or am I missing something? Please share your thoughts.

Hi Aparna,

Interesting. What I see in ColumnViewerToolTipSupport is that the CellLabelProvider can use native tool tip or not.

If it is using native tool tip, the tool tip is added to the Tree widget (not the TreeItem), presumably after it has received a SWT.MouseHover event. SWTBot would need to invoke reflection on the Tree instead of the TreeItem.

If it is not using native tool tip, the tool tip is added to its own Shell that is managed by the JFace ToolTip class. SWTBot would need to examine the Shell contents, I think the text is put in a CLabel child of the Shell.

I'm not sure if SWTBot is supposed to support these JFace features though... Do we need a JFaceBot project? Wink

Hi Patrick,
My application gives different tooltip on each treeitem.
I think that, SWTBotTreeItem.getToolTipText always returns "". This is because ReflectionInvoker.run line 53 "w.getClass().getMethod(methodName, new Class[]{})" will always give NoSuchMethodException because swt.widgets.TreeItem does not support getToolTipText(). Is it correct?
Thanks,
Aparna

Thanks. I need to get tooltip differently rather than going through SWTBotTreeItem.getToolTipText
JFaceBot is needed Smile

Thanks Patrick. Your reply helped us a lot. We were not having native tooltip. Now we implemented CellLabelProvider.useNativeToolTip() to make it native. After sending MouseHover, now I'm getting tooltip on tree.
Thanks Smile
