Description

Well here is the existing code that allows the form to follow me where ever my mouse goes.

When ever i type there is flicker. Recognition to Slick812 as this is his code that i found.

I need the flicker to be removed. If you hold down keys or start typing, the form flickers.

public
{ Public declarations }
FHookStarted : Boolean;

var
Form1: TForm1;
JHook: THandle;

function JournalProc(Code, wParam: Integer; var EventStrut: TEventMsg): Integer; stdcall;
var
Char1: PChar;
s: string;
previousy : integer;
Parent : HWND;
ThePoint : TPoint;
TheWindow : HWND;
WindowText : array[0..255] of char;

begin
{this is the JournalRecordProc}
Result := CallNextHookEx(JHook, Code, wParam, Longint(@EventStrut));
{the CallNextHookEX is not really needed for journal hook since it it not
really in a hook chain, but it's standard for a Hook}
if Code < 0 then Exit;

{you should cancel operation if you get HC_SYSMODALON}
if Code = HC_SYSMODALON then Exit;
if Code = HC_ACTION then
begin
{
The lParam parameter contains a pointer to a TEventMsg
structure containing information on
the message removed from the system message queue.
}
s := '';

{ if EventStrut.message = WM_LBUTTONUP then
begin
s := 'Left Mouse UP at X pos ' +
IntToStr(EventStrut.paramL) + ' and Y pos ' + IntToStr(EventStrut.paramH);
// Form1.ProcessFirefox;
end; }

if EventStrut.message = WM_LBUTTONDOWN then
begin
s := 'Left Mouse Down at X pos ' +
IntToStr(EventStrut.paramL) + ' and Y pos ' + IntToStr(EventStrut.paramH);
end;

{ if EventStrut.message = WM_RBUTTONDOWN then
begin
s := 'Right Mouse Down at X pos ' +
IntToStr(EventStrut.paramL) + ' and Y pos ' + IntToStr(EventStrut.paramH);
end; }

{ if (EventStrut.message = WM_RBUTTONUP) then
s := 'Right Mouse Up at X pos ' +
IntToStr(EventStrut.paramL) + ' and Y pos ' + IntToStr(EventStrut.paramH); }

if (EventStrut.message = WM_MOUSEWHEEL) then
begin
// s := 'Mouse Wheel at X pos ' + IntToStr(EventStrut.paramL) + ' and Y pos ' + IntToStr(EventStrut.paramH);
end;

{ if (EventStrut.message = WM_MOUSEMOVE) then
s := 'Mouse Position at X:' +
IntToStr(EventStrut.paramL) + ' and Y: ' + IntToStr(EventStrut.paramH); }

{ if (EventStrut.message = WM_MOUSEHOVER) then
s := 'Mouse Hover at X:' +
IntToStr(EventStrut.paramL) + ' and Y: ' + IntToStr(EventStrut.paramH); }
// if s <> '' then
// Form1.ListBox1.ItemIndex := Form1.ListBox1.Items.Add(s);
end;
Form1.Left := EventStrut.paraml + 150;
Form1.Top := EventStrut.paramH + 50;
end;
