It didn't used to do this until I updated Lazarus about a month ago. I
didn't notice the problem right away.
Create a new project.
Drop a maskedit on it.
Set the mask to something like "00/00/0000"
Set the visible property of the maskedit to false
Drop a button on the form
Add the following code to the onclick:
MaskEdit1.Text := '05/06/2003';
MaskEdit1.Visible := True;
Run the app.
When you click the button the maskedit appears, but does not have any
contents.
Click the button again, and the contents appear.
Any "text" property set before it's visible (and this includes when it's
to appear on a modal form) won't appear. Once it's been created and
displayed once, you can hide, change and reshow to your hearts content
without problem. It's that first time that it doesn't work right.
Just follow the Text property with find declaration and wou will see, that maskedit uses SetTextBuf and this does not do anything, unless the Handle is created. I fixed maskedit to use 'inherited Text' if no handle is allocated.
But if I remember right, you implemented maskedit. So maybe you can fix another bug:
Doing the above steps resulted for me in MaskEdit1.Text='05-__-____'.
