Mouse behaviour

[Fredo]

Hi,

1.
I try to change the mouse's behaviour with the DrawingNavigator.
I would like to be able to move the drawing on the left click instead of the right click.
So I change the MouseDown and MouseMove methods, which seems to work fine, the MovePictureRect is called properly.
But the drawing is repainted only when the button is released for the left button when it is still repainted during the move for the middle button !?

2.
Is there any simple way to know which entity is under the mouse? Like focus or hovering entity?

Thank you.

Hello Fredo.
Please note, we strongly not recommend to modify any source code methods.
We tried to modify MouseDown and MouseMove methods to receive mouse buttons inversion. The required behavior was received after mbLeft/mbRight and ssLeft/ssRight displacements. The drawing was repainted similarly for middle and left buttons with Viewer application. Please check your modifications.

There is no a simple way to know which entity is under the cursor. You can use TsgDrawingNavigator.GetDrawingCoords to receive drawing coordinates for the cursor. However detecting an underlying entity is not a trivial task.

Thanks, I find my problem, it was the PerformCancel method.
