Reading form's coordinates?This is a discussion on Reading form's coordinates? within the Delphi forums in Programming Languages category; Hello I'd like to display a form, and when the user clicks on a button, display a second form that will overlay the first one. So I need to read the first form's coordinates (x,y,width,height). I googled the archives of this ng, but didn't find the answer. Does Delphi provide a function for this, or do we need to call a Win32 API? Thank you.... | ||||||||

Did you never notice the Top, Left, Width and Height properties of a form? IN fact about every control has these properties. Top and Left are relative to the parent controls client area. For a form with no parent they are relative to the screen. -- Peter Below (TeamB) Don't be a vampire (http://slash7.com/pages/vampires), use the newsgroup archives : http://www.tamaracka.com/search.htm http://groups.google.com |

For a form with no parent they are relative to the screen. Or even simpler. Form2.BoundsRect := Form1.BoundsRect But I would recommend using a single form and create the two alternative views using something like a page control or frames. -- Marc Rohloff [TeamB] marc -at- marc rohloff -dot- com |

IIRC your code works but looks ugly on multi head environments (the border might be visible on another screen). > But I would recommend using a single form and create the two > alternative views using something like a page control or frames. Me, too. However IIRC even Microsoft uses another window with same position and size on top of the main window for the print preview in IE7 :-) -- Jens Gruschel http://www.pegtop.net |
