GdViewer layout bugs (up to the latest v5.12.0)

[Slava]

Hello,

I came across 2 bugs in the layout/positioning in GdViewer.

1. Scrollbars wrongly positioned
2. Viewer disappears if height is <50% of container control height

I have created a test application (see sceenshot attachment) and send to esupport@
resize to see the difference

Kind Regards,
Slava

Hi,

With Delphi 7 it is working. i suppose you are trying to use a kind of new alignment feature provided by latest version of Delphi which are is compliant with the GdViewerCnt control.

Kind regards,

Loic,

This occured indeed after the project upgrade from Delphi 7 to Delphi 2007. However there were no new properties used or changed. Both scrollbars now appear according to Top-Left corner of the container instead of Top-Left corner of GdViewer itself.

I have implemented a workaround by placing the viewer in a separate container with no borders/margins etc., so this is not critical. At least you are aware of this compatibility issue.

Kind regards,
Slava

Thank you Slava.

I will try to reproduce this behavior with Delphi 2010 I just acquired. But I think I will not be able to make something...

Kind regards,

Loïc
