Hi, A bug was reported that TCanvas.Rectangle is incompatible to Delphi, but somebody suggested that this was rather a Delphi bug.
For the complete story see: http://www.freepascal.org/mantis/view.php?id=8342 In a note I wrote: The canvas routines in Delphi are inspired by the winapi for device contexts. See http://msdn2.microsoft.com/en-gb/library/ms533879.aspx [^] for the winapi documentation. It states that "The rectangle that is drawn excludes the bottom and right edges." Somewhere else this is explained as nRightRect-nLeftRect should be considered as width. It is an easy to make this method work Delphi compatible by removing the +1 in TWin32WidgetSet.Rectangle. But I hesitate to do, because I don't know how many Lazarus code depends on the Delphi incompatibility. The questions to be answered are: Should LCLIntf.Rectangle do the same as Windows.Rectangle? Should TCanvas.Rectangle(0,0,1,1) draw an 1x1 (as Windows.Rectangle does) rectangle or a 2x2 rectangle (as Lazarus does currently)? What is the current behavior for other widget sets? So what do you think?
