Hello all, I've upgraded to TKP 13.0.0 recently (from 11.2.2). It seems like the CXTPPopupControl class now uses the 'UpdateLayeredWindow' call an as a result my own derived popup control is not displaying properly. I have a CXTPPopupControl derived class to which I set the background bitmap (32 bit with alpha). I also use one CXTPPopupItem derived class to display text on top of this background image. In 11.2.2 this worked fine. In 13.0.0 I no longer see the popup item text? When I turn off the WS_EX_LAYERED property then I see my text. I haven't played with 'UpdateLayeredWindow' before. I read on various forums that children of a layered window don't get the paint message. I do see the painting being called for my text-based popup item... but no text is displayed. Can someone shed some light on what I need to do in order to get my text to display on top of the background image again? Thanks, Peter ------------- Product: Xtreme ToolkitPro version 13.0.0 Platform: Windows XP (32bit) - SP 3 Language: C++ (MFC) |

Anyone had a chance to figure this out? I really need to fix this issue.  Here are a few more details: My derived CXTPPopupControl class uses the xtpPopupThemeCustom theme. I call SetBackgroundBitmap specifying the ID of the one and only image I load in the control's Image manager (this bitmap is 32 bits). I then add a simple CXTPPopupItem that is used to display a message (text only). The popup ctrl displays nicely; the rounded edges of the bitmap render just fine. I'm just not seeing the text item within it? Thanks for your time, Peter. ------------- Product: Xtreme ToolkitPro version 13.0.0 Platform: Windows XP (32bit) - SP 3 Language: C++ (MFC) |

Hello,
Yes if you use 32 bit alpha bitmap Popup control use Layers and can't draw any text. Just set simple 24 bit bitmap to make custom shape. ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |
