Description

TCustomDrawState specifies a custom drawing state.

TCustomDrawState indicates state information that can affect how a control is drawn.

It includes a set drawn from the following values:

Value	Meaning
cdsSelected	The control or item is selected.
cdsGrayed	The control or item appears unavailable.
cdsDisabled	The control or item is disabled.
cdsChecked	The item appears checked.
cdsFocused	The control or item has input focus.
cdsDefault	The item is the default item.
cdsHot	The item is under the mouse and the HotTrack property is True.
cdsMarked	The item is marked (marked items appear shaded by default.)
cdsIndeterminate	The item is neither selected, nor unselected.
cdsShowKeyboardCues	The item uses the keyboard cues when being drawn.
cdsNearHot	The item is part of a control that is in an "under the mouse" state, but the item is not "under the mouse" itself.
cdsOtherSideHot	The item is part of a split button that is in an "under the mouse" state, but the item is not "under the mouse" itself.
cdsDropHilited	The item is the drop target of a drag-and-drop operation.

To test the state—for example of an item of the type TListView—you should write the following code for Delphi.

procedure TForm1.ListView1CustomDrawItem(Sender: TCustomListView;
  Item: TListItem; State: TCustomDrawState; var DefaultDraw: Boolean);
begin
//get the state
if (cdsFocused in State) then
    ShowMessage('ok');
//set the state
  State := [cdsSelected];
end;
