Transparent desktop icon text

[Tom Bradshaw]

Hi,
I have seen some programs that can make the background of the icon text
on the windows desktop transparent, how is this done?

Thanks

Set the Brush to bsClear to write text with a transparent background.

Windows desktop icons, how do you make the text background for 'Recycle
Bin', 'My Computer', etc. transparent?

I thought you were talking about text in general using Delphi, not the specific
Windows desktop
icons. Unless there's a registry entry somewhere that controls this, I'm not
aware of how
you can change the transparency of a desktop icon's text from inside a Delphi
program.

You might try asking in borland.public.delphi.winapi.

Try this:

function EnumChildProc(AHandle: hWnd): BOOL; stdcall;
// callback for EnumChildWindows.
var
tmpS: string;
theClassName: string;
clrText: Integer;
begin
Result := True;
SetLength(theClassName, 256);
GetClassName(AHandle, PChar(theClassName), 255);
tmpS := PChar(theClassName);
if Pos('SysListView32', tmpS) > 0 then
begin // ColorToRGB(clNone)
clrText := -1; // Desired background color
SendMessage(AHandle, LVM_SETTEXTBKCOLOR, 0, clrText);
clrText := $FFFFFF; // Desired text color (BGR)
SendMessage(AHandle, LVM_SETTEXTCOLOR, 0, clrText);
end;
end;

procedure TForm1.Button1Click(Sender: TObject);
const
WM_REFRESH_DESKTOP = $A065;
var
WndClass: array[0..50] of char;
h: THandle;
begin
WndClass := 'Progman';
h := FindWindow(@WndClass[0], 'Program Manager');
EnumChildWindows(h, @EnumChildProc, 0);
SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, 0, 0);
end;

Icon Editors assign a specifc color (usually 0,0,0) to the "background",
this color or color index is used by the OS to OR against the background.

Tom,

What Finn said. Basically, you get the window handle of the SysListView32
that represents the desktop, and you send it an LVM_SETTEXTBKCOLOR
message, setting the background color to -1. That causes it to be
transparent.

Note that this is an impermanent state of affairs. Any change to the
desktop properties will reset the text background color to normal. Also,
it doesn't work when you've checked Active Desktop | View as Web Page for
the desktop.
