• May 23, 2019  Tips for Multi-Resolution Delphi Applications. If you're not going to scale the form, set. When its parent is resized, the control holds its position relative to the edges to which it is anchored. If a control is anchored to opposite edges of its parent, the control stretches when its parent is resized.

Delphi Scale Form Controls Relative Model

To enable runtime user movement and resizing of controls on a form with a mouse, three need special handling: OnMouseDown, OnMouseMove, and OnMouseUp.In theory, let's say you want to enable a user to move (and resize) a button control, with a mouse, at run-time. Firstly, you handle the OnMouseDown event to enable the user to 'grab' the button.

Next, the OnMouseMove event should reposition (move, drag) the button. Finally, OnMouseUp should finish the move operation. Dragging and Resizing Form Controls in PracticeFirstly, drop several controls on a form. Have a CheckBox to enable or disable moving and resizing controls at run-time.Next, define three procedures (in the interface section of the form declaration) that will handle mouse events as described above: typeTForm1 = class(TForm).procedure ControlMouseDown(Sender: TObject;Button: TMouseButton;Shift: TShiftState;X, Y: Integer);procedure ControlMouseMove(Sender: TObject;Shift: TShiftState;X, Y: Integer);procedure ControlMouseUp(Sender: TObject;Button: TMouseButton;Shift: TShiftState;X, Y: Integer);privateinReposition: boolean;oldPos: TPoint.

Automatic scaling seeks to ameliorate these problems by automatically resizing the form and its child controls according to the relative font size or display resolution. The Windows operating system supports automatic scaling of dialog boxes using a relative unit of measurement called dialog units.
