[Lazarus] GetFormImage bug
Hi guys, I am not very sure on how I can describe this... I have a thumbnail section in my main program form. In the forms, I use GetFormImage to make an image and send it to the mainform. The bug is that some components are not visible in this image. TDBGrid is one and a custom component derived from TBitBtn is another. I use the latest stable Lazarus 1.2.2 with FPC 2.6.4 on windows7, both 32 and 64 bit Regards, Chris-- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Perhaps you need to share the code that drops parts of the bitmap (and perhaps the lfm of the imaged form as well). -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] GetFormImage bug
Since the problem is in my code I will try to figure it out and report any results. The system is a bit complex to post everything, but the basics are the same. If I fail in this I will try to duplicate the problem in smaller forms, so I can post a bug report Thanks for testing Howard :) From: Howard Page-Clark Sent: Tuesday, May 13, 2014 7:44 PM To: lazarus@lists.lazarus.freepascal.org Subject: Re: [Lazarus] GetFormImage bug On 13/05/2014 16:49, Chris Crori wrote: I have a thumbnail section in my main program form.
