Mouse Wheel

[alfons]

Hi, i try to understand your Viewer demo.
How do you implement using Mouse Wheel and right mouse button?
I have modified viewer demo to view dxf-File on a second tabsheet but mouse wheel has no function.

We use our own sgDrawingNavigator component for displaying CADImage with scale possibility.
There is no any problems with mouse using.
DrawingNavigator properties:

Code: Select all

property ScalingOnMouseWheel: Boolean read FScalingOnMouseWheel write FScalingOnMouseWheel; 

- mouse whill scaling is True by default. To disable set False.

Code: Select all

property RectZooming: Boolean read FRectZooming write SetRectZooming default True; 

- mouse selection scaling. To disable set False.

- You should handle OnMouseWheel event on MainForm (the form where navigator is)
- Navigator contains such events as OnClick, OnDblClick, OnMouseDown #1080; OnMouseUp.

If it does not solve your problem, please send us your demo (support@cadsofttools.com) and explain, what you would like to get.

On first Register Mouse is ok. On second register mouse has no
