The TabbedTextOut function writes a character string at a specified location, expanding tabs to the values specified in an array of tab-stop positions. Text is written in the currently selected font.
LONG TabbedTextOut(
HDC hDC, |
// handle of device context |
int X, |
// x-coordinate of starting position |
int Y, |
// y-coordinate of starting position |
LPCTSTR lpString, |
// address of string |
int nCount, |
// number of characters in string |
int nTabPositions, |
// number of tabs in array |
LPINT lpnTabStopPositions, |
// address of array for tab positions |
int nTabOrigin |
// x-coordinate for tab expansion |
); |
Windows 95: A tab stop can be specified as a negative value, which
causes text to be right-aligned on the tab stop rather than left-aligned.
If the function succeeds, the return value is the dimensions, in logical units, of the string. The height is in the high-order word and the width is in the low-order word.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
If the nTabPositions parameter is zero and the lpnTabStopPositions parameter is NULL, tabs are expanded to eight times the average character width.
If nTabPositions is 1, the tab stops are separated by the distance specified by the first value in the lpnTabStopPositions array.
If the lpnTabStopPositions array contains more than one value, a tab stop is set for each value in the array, up to the number specified by nTabPositions.
The nTabOrigin parameter allows an application to call the TabbedTextOut function several times for a single line. If the application calls TabbedTextOut more than once with the nTabOrigin set to the same value each time, the function expands all tabs relative to the position specified by nTabOrigin.
By default, the current position is not used or updated by the TabbedTextOut function. If an application needs to update the current position when it calls TabbedTextOut, the application can call the SetTextAlign function with the wFlags parameter set to TA_UPDATECP. When this flag is set, Windows ignores the X and Y parameters on subsequent calls to the TabbedTextOut function, using the current position instead.
