L_INT EXT_FUNCTION L_PntApplyText (pPaint, UserDC, prcRect)
|
pPAINTHANDLE pPaint; |
/* pointer to a paint handle */ |
|
HDC UserDC; |
/* handle to the device context */ |
|
LPRECT prcRect; |
/* pointer to a RECT structure */ |
Writes a character string in the specified rectangle.
|
Parameter |
Description |
|
pPaint |
Pointer to a paint handle. |
|
UserDC |
Handle to a device context, such as a screen, to use as a display surface. This parameter can also be NULL. The mapping mode of the device context must be MM_TEXT. |
|
prcRect |
Pointer to a RECT structure that contains the bounding rectangle in which to write the text. This rectangle will also be used to align the text. |
Returns
|
SUCCESS |
The function was successful. |
|
< 1 |
An error occurred. Refer to Return Codes. |
Comments
The text will be drawn using the current text properties. To determine the current text properties, call L_PntGetProperty. To set or change the current text properties, call L_PntSetProperty. For more information on the text properties, refer to the PAINTTEXT structure.
The text string and font must be set before calling this function. Otherwise, the function will return an error.
If UserDC is not NULL, the toolkit will paint the text on the specified device context. If UserDC is NULL, the text will not be painted on a device context.
If a bitmap has been set using the L_PntSetMetrics function, the text will be drawn on the specified bitmap. If UserDC is not NULL and a bitmap has been set using the L_PntSetMetrics function, then the text will be drawn to both the device context and the bitmap.
The font handle in the hFont field of the PAINTTEXT structure should still be valid after calling this function.
