My guess is that your buttons are not becoming invisible, they're just slightly to the right/bottom of the visible form; In some circumstances (haven't figured out how) the form that hosts the controls gets resized and the buttons don't get a chance to change the position on screen. After this initial change in form dimensions the buttons end up outside the visible area (Button.Left > Form.Width) and when you maximize the form the button does it's best to stay anchored to the right: no matter what you do after this initial problem, the button stays outside the visible area!
Fix: Try setting Left and Top for the buttons from code (ie: don't rely on anchors). Try doing it from an button / menu item (for testing) and then figure out an event that works for you. Example: From the OnShow, OnResize. -- Cosmin Prund > -----Mesaj original----- > De la: delphi-boun...@elists.org [mailto:delphi-boun...@elists.org] În > numele chris.mo...@biuk.co.uk > Trimis: Thursday, November 19, 2009 9:25 AM > Către: Delphi@elists.org > Subiect: Disappearing buttons > > Hello List. > > I have an application with three tButtons. as certain things happen, > the buttons become enabled or disabled.
