We have an editor built using the GEF framework and recently we ran into an issue when dealing with multiple display monitors. Take the following setup: 2 monitors next to eachother, with our application running maximized on the left monitor. When hovering a figure close to the right edge, a tooltip pops up but if it is long enough, it will extend onto the second display, making it hard to read the message.
The tooltip's location is calculated using the ToolTipHelper class which doesn't seem to take multiple monitors with display extension into account. The debugger showed that the clientArea was in fact 3840x1080, which corresponds to both monitors.

It seems impossible to use a custom ToolTipHelper without hacking too much into the Draw2D framework.


Reproducible: Always
