Hello

Please specify, the problem with glyphs drawing exists only in the TrkSmartTabs and in the TVirtualStringTree components?

Can you make a demo and upload here, please?

Hi!

I will try to create a demo asap, until then I try to specify:

the problem with the TrkSmartTabs is that sometimes the icons on the tabs disappear, then they appear again while in the code there is nothing that could be responisble for this.

On picture “p1.png” you can see the abscence of icons. Then I move my mouse above the button below it (with the little clock sign), and when moving back above the tabs, the icons reapper at once, like on picture “p2.png”. Then it happens again and again: icons disappear whenn for example changing tabs, then reappear after hovering over a button.

The problem with TVirtualStringTree is very similar: at first I cannot see any icons (p3.png), then I start moving the mouse over the TVirtualStringTree, and they appear (p4.png).

The crucial problem is that of the TVirtualStringTree, as we use them everywhere, while I can use another tabcontrol if I have to (however I would really like to avoid this situation…)

Hi!

I created a test application in Delphi 10.2, which mimics the layout and behaviour of my app.

Unfortunately the TrkSMartTabs component does not show the error in this app. However your can clearly see that the images drawn onto the area of TVirtualStringTree are different from what you can see, if you look at it in the imagelist.

I attached the folder for TrkSmatrTabs, too.

I appreciate your help,

Béla

Thank you

Really, reason of the issue is in the strange work with BlendColor property by the VirtualStringTree.

I will add the global acIgnoreBlendColor variable declared in the acAlphaImageList unit.

You will be able to change this behavior by changing of the variable to True.

Ok, thank you for your prompt help.

Not to urge you, but when do you think this fix will be available?

It's published already, you can try it.
