Set new text to wxTextCtrl smoothly

Hi,

I have a wxTextCtrl where I add lines of text from time to time. These new lines are added in front of the exiting text so that all other scroll down.

Setting of the new text is done with SetValue(). Using Windows that works well but under Linux the display and the scroll bar of the text controls flickers heavily.

So how can I set the text more smoothly?

Do Freeze() / Thaw() help?

No, that does not change anything. I tried to call it for the wxTextCtrl and for the parent window and both did not help.

try ChangeValue()?

Same result, it does not help.

After this is not a serious issue I'll have a look if I can solve that later...

or you can define your textctrl.
derived from scrolledwindow, draw the text yourself with the wxAutoBufferedPaintDC,that would be better.

the text wrapper could reference the wxTextctrl.
