Here you can see it:

Please take a look at the toolbars. I think because of the video compression, it's not visible alyways in this clip when showing the dialog, but always when closing it. But in real life it occurs every time…

Hello,

I just found out something for myself… In Line 6325 of sSkinProvider.pas (TsSkinProvider.AC_WMNCActivate) there are 2 lines of code:

Code:

RedrawWindow(Form.Handle, nil, 0, {RDW_ALLCHILDREN or }RDW_INVALIDATE or RDW_UPDATENOW or RDW_NOERASE or RDW_FRAME);
// RedrawWindow(Form.Handle, nil, 0, RDW_ALLCHILDREN or RDW_INVALIDATE or RDW_UPDATENOW or RDW_NOERASE);

The second one is commented out. If I change it, comment out the first one and reactivate the second one, it will be much better. There's still a light flickering visible but by far not as strong as with the other line. As I don't know the impact of these both lines, of course I will change it back to the official version.

Can I change maybe something in the toolbar component? This effect is only visible with SpTbx components.

Best regards

Friedemann

Hi Friedemann

Does LockWindowUpdate(Form1.Handle) do the trick?

where do you think I should insert this?

BTW: It seems for me at the moment that this behaviour depends on the Windows version. On another system there's no flickering (I think Windows 7). I'm using Windows 8.1. I will check it tomorrow in my office. Very strange…

I would use the OnClick event of the toolbar item. Have you tried

{…}

SendMessage(Panel1.Handle, WM_SETREDRAW, 0, 0);

Open your dialog here

{…}

SendMessage(Panel1.Handle, WM_SETREDRAW, 1, 0);

RedrawWindow(Panel1.Handle, nil, 0, RDW_FRAME or RDW_INVALIDATE or RDW_ALLCHILDREN or RDW_NOINTERNALPAINT);

in that event already?

Hi Uwe,

but then I have to lock a lot of panels always 😉 And it also occurs when switching to another application and back, always when the main form will be activated/deactivated.

Just replace Panel1 with Form1, or you follow my advice from a few weeks ago and finally ditch SpTbx… 😀

NO! 😀 I will definitely not! It offers a lot features which I'm using and which aren't available in standard toolbar and menu. And I really hope to get this problem solved without ditching components…
