In the series: “how to lose time by fixing GXT stuff that should work but doesn’t“, today we address tooltips on individual TreeItems. If you ever tried to set a tooltip on a TreeItem and got frustrated because it didn’t work, you might find this post interesting:

As usual, a lot of time is spent working around GXT oddities, only to find new ones… For example, Component.setToolTip takes not a ToolTip, but a ToolTipConfig. Additionally, it instantiates the ToolTip. There is no way of passing an already constructed ToolTip to a Component, which means you can’t use a subclass of ToolTip. (Hint for GXT developpers: Law of Demeter)
The link you posted for solution is not working.. Can you please post the solution as well.
Sorry, Sencha has changed their forum and apparently it’s not accessible any more…
