D4: fsNormal to fsMDIForm loses controls

[mkudra]

Changing a working form's style from fsNormal to fsMDIForm cause the disappearance of existing controls (e.g. SpeedButtons).<br><br>Seems so familiar, but cannot locate in books/FAQs/TIs on hand ...

Eeeeeuhm... You're NOT supposed to change the FormStyle property at runtime!!!

 

[mkudra]

Did not state at runtime, did not change at runtime, but under Property Inspector at design time ...<br><br>Controls show on form designer, do not show on form at runtime ....

 

[mkudra]

And stranger still, the hint balloon appears at run time when hovering over where the control is located at design time, and clicking that area activates the button ...

 

[mkudra]

Never mind - placed a TPanel under the SpeedButtons, and they show now.&nbsp;&nbsp;TButtons never disappeared ....

Check z order of components

Speedbuttons were on top of form, no other components were over/underlaid, form was owner & parent ...<br><br>Thanks.
