I have a Vista-skin enabled form view with a number of controls. When the main window is resized, the view is also resized and all controls are resized according to the anchors defined by my calls to SetResize(...).

It works, but during resize the group boxes flicker. It has something to do with the transparency setting; when I remove it the flickering goes away. Please note that I have the "Show windows contents while dragging" option enabled.

Any ideas?

Thanks!

Hi,

use CXTResizeGroupBox classes:

Add CXTResizeGroupBox m_groupColor;

and

m_groupColor.SubclassDlgItem(IDC_GBOX_COLOR, this);

DDX_Control(pDX, IDC_GBOX_COLOR, m_groupColor);

That's the same as the above, right?

It does not help. As long as transparency is enabled, it flickers on resize :(

Hi,

What do you mean by "transparency is enabled". How do you enable it?

Via the resource editor: WS_EX_TRANSPARENT

As far as I know that style is needed for correctly painted group boxes when skinning is enabled.

Hi,

No. You don't need this style.

If I don't set the transparent style, the group box is painted in black. It is painted correctly if set, though it flickers when resizing the window.

Hi,

I opened our Samples\PropertyGrid\GridSample sample that has Resize functionality and resized groub boxes. I added XTPSkinManager()->LoadSkin("Styles\\Vista.cjstyles");

no flickers, no black boxes.
