QueryObject:Int32 object:Int32, query_id:Int32

Parameter	Type	Default	Description
object	Int32	required	A window, gadget or font.
query_id	Int32	required

Description

In the original it gives the Windows handle behind a gadget (query 1 is the HWND, 2 the HWND of the client area, 3 the HFONT), so it can be used with the Windows API.

Differences

• All gadgets are drawn inside the one window of the program, so queries 1 and 2 give the handle of that window (an HWND on Windows) for every gadget. Fonts (3) have no handle of the operating system and give 0, and so does anything that is not a gadget.

Examples

Graphics 320, 240, 32, 2
win = CreateWindow("Query", 20, 20, 240, 100, Desktop(), 3)
SetGadgetText win, "Handle " + QueryObject(win, 1)
Repeat
Until WaitEvent() = $803
