Comments
pnHandle
PSHORT
Handle to a GX11X0 board.
hwndParent
HWND
Panel parent window handle. A value of 0 sets the desktop as the parent window.
nMode
SHORT
The mode in which the panel main window is created. 0 for modeless window and 1 for modal window.
phwndPanel
HWND
Returned window handle for the panel.
pnStatus
PSHORT
Returned status: 0 on success, negative number on failure.

Comments

The function is used to create the panel window. The panel window may be opened as a modal or a modeless window depending on the nMode parameters.

If the mode is set to modal dialog (nMode=1), the panel will disable the parent window (hwndParent) and the function will return only after the window closes. In that case, the pnHandle may return the handle created by the user using the panel Initialize dialog. This handle may be used when calling other GX110 functions.

If a modeless dialog is created (nMode=0), the function returns immediately after creating the panel window returning the handle to the panel - phwndPanel. It is the responsibility of calling program to dispatch windows messages to this window so that the window can respond to messages.

Example

The following example opens the panel in modal mode:

 

DWORD dwPanel;

SHORT nHandle=0, nStatus;

 

GtWavePanel(&nHandle, 0, 1, &dwPanel, &nStatus);
