Summary0008346: TPageControl: Edit components are invisible - possible z-order problem
DescriptionI have a TPageControl. Add a TTabSheet, and then another. Now I add some components to open sheet - works well. Now I switch to the other tabsheet - either by clicking on the tab or by right-click -> Show Page, then try to add a TEdit component. The component seems to be invisible - apart from the grid-dots that disappears where the component is.

This only happens with some components - TLabel for instance does not appear invisible.

Happens in both gtk and gtk2.
Additional InformationI can get around it by doing the design for one sheet, then switch to the next sheet I want to work on, save the project, restart lazarus and it will open in the other sheet, so I can design that one. It is rather annoying though.
TagsNo tags attached.

This is not just in TPageControl, also got the same thing in TNotebook

Did the problem happen in a recent SVN version (say the last 4 weeks) and did it work before ?

I haven't been using lazarus for a while -- only started doing a project in it again about a month ago, maybe not even a month and I had this problem since then.

Marc, sorry for long time to respond. I have no idea when it started. I haven't used lazarus for a while, and then when I started with it again I used it in gtk2 and didn't use the notebook or page control straight away. So sorry I don't really have an answer for you.

Sorry, I didn't notice I already responded to the questions ages ago!

I've just tested with r 18681, and cannot reproduce it (gtk/gtk2).
If someone can, then please give feedback and example how it happens - in next two weeks, otherwise case will be closed ;)
