Properties
Bounds
The size and the position of the widget is condensed in the property bounds, but ou have also the traditional properties like left an width.
// the types
sizety = record
cx, cy: integer;
end;
pointty = record
x,y: integer;
end;
rectty = record
case integer of
0: (x, y, cx, cy: integer);
1: (pos: pointty; size: sizety);
end;
// the properties
property Widgetrect: rectty read FWidgetrect write SetWidgetrect;
property Pos: pointty read FWidgetrect.pos write SetPos;
property Size: sizety read FWidgetrect.size write SetSize;
property Bounds_x: integer read FWidgetrect.x write SetBounds_x;
property Bounds_y: integer read FWidgetrect.y write SetBounds_y;
property Bounds_cx: integer read FWidgetrect.cx write SetBounds_cx
{default defaultwidgetwidth} stored true;
property Bounds_cy: integer read FWidgetrect.cy write SetBounds_cy
{default defaultwidgetheight} stored true;
property Bounds_cxmin: integer read FMinSize.cx
write SetBounds_cxmin default 0;
property Bounds_cymin: integer read FMinSize.cy
write SetBounds_cymin default 0;
property Bounds_cxmax: integer read FMaxSize.cx
write SetBounds_cxmax default 0;
property Bounds_cymax: integer read FMaxSize.cy
write SetBounds_cymax default 0;
property Left: integer read FWidgetrect.x write SetBounds_x;
property Right: integer read GetRight write SetRight;
//widgetrect.x + widgetrect.cx, sets cx if an_left is set
property Top: integer read FWidgetrect.y write SetBounds_y;
property Bottom: integer read GetBottom write SetBottom;
//widgetrect.y + widgetrect.cy, sets cy if an_top is set
property Width: integer read FWidgetrect.cx write SetBounds_cx;
property Height: integer read FWidgetrect.cy write SetBounds_cy;
property MinSize: sizety read FMinSize write SetMinSize;
function WidgetMinSize: sizety;
//calls checkwidgetsize and frame.checkwidgetsize
property MaxSize: sizety read FMaxSize write SetMaxSize;
Enabled
property Enabled: boolean; default true;
Sets the widget enabled or not. Some Widgets change their look if they are not enabled, others do not.
Visible
property Visible: boolean; default true;
Sets the widget visible or hides it.
