injectMouseButtonDown returns always true

[wolfmanfx]

Hi,
I updated to CeGUI 0.7.1 and realized that injectMouseButtonDown (and all other inject methods) returns true.

The problem is in CeGUISystem.cpp line 1022 in function getTargetWindow

Code: Select all

       
if (!dest_window)
            return 0;//dest_window = d_activeSheet;


After making the change above everything works like excepted.

mmm this has also some side effects like window resizing do not work and the mousecursor disappear when hover over an editbox.

Returning the set GUI sheet as the default / catch-all target window is something we've always done.

I imagine the issue is related to changes that were made to the way the inject functions work; in 0.6.x the return values from these functions - especially the mouse related functions - were largely worthless, and required app side kludges to be able to reliably detect whether a mouse event occurred over a UI window or not - where the full screen root window is not considered as UI.

I fixed this for 0.7.x such that all mouse events are marked handled (and thus, the inject function will return true) except in the case of a root window of type DefaultWindow (class GUISheet) with the MousePassThroughEnabled property set to true - in these cases, the inject function will only return true if a subscribed event handler marked the input as handled.

So the solution should be to ensure you have a DefaultWindow as the root of the layout and set the MousePassThroughEnabled property to True.

HTH
