Forums » Prof-UIS General Discussion » Painting issue with 16 bits per pixel color mode Collapse All

my Windows system normally runs in a 16 bits per pixel graphics mode, because some of our customers also use this mode.

And we have to verify, that our applications look fine on our customer’s PC’s too.

But certain themes of Prof-UIS (2.83) don’t look well on the 16bpp mode.

Especially labels, radio buttons and check boxes, that should display a text with a transparent background, paint visible boxes instead.

You can verify this if you run one of the Prof-UIS samples (I tried with FunnyBars, and opened the About dialog), choosing one of the themes below and switch the operating systems color mode between 16 and 32 bits per pixel.

Themes that don’t look fine:

- Office 2007 (Release 2) Silver

- Visual Studio 2008

- Visual Studio 2005

- Office 2003 (without Windows XP theme colors)

- Office 2003

Themes that do look fine:

- Office 2007 (Release 2) Obsidian

- Office 2007 (Release 2) Luna-Blue

- Office 2007 (Release 1)

- Native Windows XP

- Office XP / Visual Studio .NET

- Office 2000

Is there a way to fix this without modifying Prof-UIS (too much)?

Are you going to change the behaviour in any future version of Prof-UIS?

Thanks very much!

We checked this issue in Prof-UIS 2.84 both on XP and Vista .Everything is very similar in both 32 and 16 bit per pixel modes. Could you send us a screen shot demonstrating the problem?
