Title: Panel dependent TStatusbar.OnDblClick
Question: How can I tell which panel was clicked within a TStatusbar?
Answer:
The TStatusbar haven't got any event for telling which Panel the mouse was clicked in. To get this information you can use the following code.
What is does:
1. It gets the current mouse coords
2. Loops trough all the panels testing if the mouse is inside the panel rect using the SB_GETRECT message to get the rect.
//=================================================================
procedure TMainForm.StatusBar1DblClick(Sender: TObject);
var MouseCor : TPoint;
PanelRect: TRect;
lp0 : integer;
SB : TStatusBar;
begin
if Assigned(sender) then begin
if Sender is TStatusBar then begin
GetCursorPos(MouseCor);
SB := TStatusBar(Sender);
for lp0 := 0 to SB.Panels.Count-1 do begin
SendMessage(SB.Handle, SB_GETRECT, lp0, Integer(@PanelRect));
if PtInRect(PanelRect,SB.ScreenToClient(MouseCor)) then begin
// Put code in here
// SB.Panels[lp0] was clicked
break;
end;
end;
end;
end;
end;
