Ansonnsten hatte ich das mal irgendwo gefunden:
Delphi-Quellcode:
uses Commctrl;
{....}
const
TTS_BALLOON = $40;
TTM_SETTITLE = (WM_USER + 32);
var
hTooltip: Cardinal;
ti: TToolInfo;
buffer : array[0..255] of char;
{....}
procedure CreateToolTips(hWnd: Cardinal);
begin
hToolTip := CreateWindowEx(0, 'Tooltips_Class32', nil, TTS_ALWAYSTIP or TTS_BALLOON,
Integer(CW_USEDEFAULT), Integer(CW_USEDEFAULT), Integer(CW_USEDEFAULT),
Integer(CW_USEDEFAULT), hWnd, 0, hInstance, nil);
if hToolTip <> 0 then
begin
SetWindowPos(hToolTip, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE or
SWP_NOSIZE or SWP_NOACTIVATE);
ti.cbSize := SizeOf(TToolInfo);
ti.uFlags := TTF_SUBCLASS;
ti.hInst := hInstance;
end;
end;
procedure AddToolTip(hwnd: DWORD; lpti: PToolInfo; IconType: Integer;
Text, Title: PChar);
var
Item: THandle;
Rect: TRect;
begin
Item := hWnd;
if (Item <> 0) and (GetClientRect(Item, Rect)) then
begin
lpti.hwnd := Item;
lpti.Rect := Rect;
lpti.lpszText := Text;
SendMessage(hToolTip, TTM_ADDTOOL, 0, Integer(lpti));
FillChar(buffer, SizeOf(buffer), #0);
lstrcpy(buffer, Title);
if (IconType > 3) or (IconType < 0) then IconType := 0;
SendMessage(hToolTip, TTM_SETTITLE, IconType, Integer(@buffer));
end;
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
CreateToolTips(Form1.Handle);
AddToolTip(Memo1.Handle, @ti, 1, 'Tooltip text', 'Title');
end;
{
IconType can be:
0 - No icon
1 - Information
2 - Warning
3 - Error
}
