Hello All!

Help me please. I have problem. I needed to create moving on the timer, textual component. I can not use TLabel, because it blinks during drawing. TStaticText does not blink, but it not transparent. Adjust StaticText.ComponentStyle in not csOpaque does not help.
Prompt me pls, how do I decide this problem?

Thank, Nick G.

Double buffer it! Create 2 TLabels on the the same positon. When an update has to be done update the invisible one with new text, then make it visible and make the old one invisible. So at every update you switch between the 2 TLabels.

Give it your best shot and let me know if it works!

Or try this (cleaner than having two of them...

SetWindowLong(StaticText1.Handle, GWL_EXSTYLE,
                        GetWindowLong(StaticText1.Handle, GWL_EXSTYLE)                                                OR WS_EX_TRANSPARENT);

Cheers,

Raymond.

Maybe you should use this too:

SendMessage(form1.handle, WM_SETREDRAW, 0, 0); to lock redraw
SendMessage(form1.handle, WM_SETREDRAW, 1, 0); to unlock redraw

Or try to write directly with form1.canvas.textout and change form1.canvas.textflags to your needs.
