This message is sent by an application to set the tab-stop positions in a list box.
LB_SETTABSTOPS wParam= (WPARAM) cTabs ; lParam= (LPARAM)(LPINT) lpnTabs ;
Parameters
- cTabs
- Specifies the number of tab stops in the list box.
- lpnTabs
- Long pointer to the first member of an array of integers
containing the tab stops, in dialog template units. The tab stops
must be sorted in ascending order; backward tabs are not allowed.
Return Values
TRUE indicates that all the specified tabs are set. FALSE indicates otherwise.
Remarks
To respond to the LB_SETTABSTOPS message, the list box must have been created with the LBS_USETABSTOPS style.
If cTabsparameter is 0 and lpnTabsis NULL, the default tab stop is two dialog template units. If cTabsis 1, the list box will have tab stops separated by the distance specified by lpnTabs.
If lpnTabspoints to more than a single value, a tab stop will be set for each value in lpnTabs, up to the number specified by cTabs.
The values specified by the lpnTabsparameter are in dialog template units, which are the device-independent units used in dialog box templates. To convert measurements from dialog template units to screen units (pixels), use the MapDialogRectfunction.
