An application sends a ZGM_SETROWNUMBERFONT message to change the font used to display the row number in the ZeeGrid.
ZGM_SETROWNUMBERFONT
wParam = (LPARAM)(int) iFPIndex; //Font palette index
lParam = 0; //not used; must be zero
This message does not return a value.
The row number column will automatically size itself to hold the number of digits required to display the largest row number currently in the ZeeGrid. This width will be determined by the font size of the selected font palette.
