DBGrid columns no resize at run-time

[pat03uk]

I can't resize the columns of a DBGrid at run time using the mouse.

I get the resize cursor when hovering over the header junction between columns but no resize.

This is latest Lazarus on a Mac.

Hi pat03uk,

I was able to reproduce this behavior. If you have a silent exception on the OnMouseDown event linked to the DBGrid, you will not be able to resize columns.
Check if you have any overloaded events related to the mouse action on your DBGrid that are not raising exception.

Code: Pascal  [Select][+][-]

1.  
2. Procedure TfmMainDemo.grdProjectMouseDown(Sender: TObject; Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
3. Begin
4.    // Simulate a silent exception
5.    Abort;
6. End;  
7.  
8.

Thanks for that. I will check but I have since tried KDBGrid, RXDBGrid which work as expected. Then I went back to DBGrid and that now worked fine as well. So I don't know what the problem was.
