An application sends a ZGM_SETLEFTINDENT message to set the left indent of each cell in the ZeeGrid.
ZGM_SETLEFTINDENT wParam = (WPARAM) (DWORD) dwIndent; //pixels to indent lParam = 0; //not used; must be zero
This message does not return a value.
The left indent is set to 2 pixels by default.
The left and right indent values are global indents. All cells will be indented by the specified number of pixels.
