Summary: Antialiasing subpixel thickness lines is hard work and requires a number of dirty tricks to output what we intuitively expect to see. The extra effort you’re seeing is almost certainly due to antialiasing. When the line thickness is less than one pixel and the line doesn’t sit squarely at the center of a row … Read more

If someone can confirm it works, I’d appreciate. unit fOpen; interface uses {$IFDEF MSWINDOWS} Winapi.ShellAPI, Winapi.Windows; {$ENDIF MSWINDOWS} {$IFDEF POSIX} Posix.Stdlib; {$ENDIF POSIX} type TMisc … Read more

The following function is what you need to override: procedure DoAddObject(const AObject: TFmxObject); override; This is called when a control is added to your control. Override this function so … Read more
I tried your code, it takes 00:10:439 on my PC on XE3 to fill screen with cells. By disabling these lines: //ProgressBar.Value:= ProgressBar.Value + 1; //Caption:= ‘Elapsed time: ‘ + FormatDateTime(‘nn:ss:zzz’, Time – T) + // ‘ (min:sec:msec) Cells: ‘ + IntToStr(Trunc(ProgressBar.Value)); … //Application.ProcessMessages; This goes down to 00:00:106 (!). Updating visual controls (such as … Read more
It is possible using NSPanel with NSNonactivatingPanelMask flag. The NSView of fmx form should become child of NSPanel. I have written a helper class which works for both Windows and Mac platforms (Works on XE4): unit NoActivateForm; interface uses Fmx.Forms, Fmx.Types {$IFDEF POSIX} , Macapi.AppKit {$ENDIF} ; type TNoActivateForm = class private form: TForm; {$IFDEF … Read more
