The PAINTTEXT structure contains information for drawing text.
Member |
Description |
|
nSize |
Size of this structure. |
|
dwMask |
Flags that indicate which structure members contain valid information. Possible values are: |
|
|
Value |
Meaning |
|
PTF_ALL |
All the fields contain valid data. |
|
PTF_TEXT |
The pszText field contains valid data. |
|
PTF_FONT |
The hFont field contains valid data. |
|
PTF_BORDERBRUSHSTYLE |
The nBorderBrushStyle field contains valid data. |
|
PTF_BORDERWIDTH |
The nBorderWidth field contains valid data. |
|
PTF_BORDERCOLOR |
The crBorderColor field contains valid data. |
|
PTF_BACKGROUNDSTYLE |
The nBackgroundStyle field contains valid data. |
|
PTF_BACKGROUNDCOLOR |
The crBackgroundColor field contains valid data. |
|
PTF_BACKGROUNDTILEBITMAP |
The pBackgroundTileBitmap field contains valid data. |
|
PTF_ALIGNMENT |
The nAlignment field contains valid data. |
|
PTF_OPACITY |
The nOpacity field contains valid data. |
|
PTF_TEXTURE |
The pTexture field contains valid data. |
|
PTF_TRANSFORMINFO |
The TransformInfo field contains valid data. |
|
The values can be combined using the bit-wise OR operator ( | ). |
|
pszText |
Character string that contains the string to be drawn. The toolkit will copy this string to its internal data. |
|
hFont |
The font used to paint the text. This font should be a true type font. The toolkit will not copy this handle. Therefore, this font handle should still be valid after setting this field. |
|
nBorderBrushStyle |
An enumerated type that indicates the text border (outline) style. For a list of possible values, refer to PAINTTEXTBORDERBRUSHSTYLE. |
|
nBorderWidth |
Value that indicates the width or the text border, in pixels. Valid values are 1 to 100. |
|
crBorderColor |
The COLORREF value that specifies the color to use to draw the text border (outline). |
|
nBackgroundStyle |
An enumerated type that indicates the text background style. For a list of possible values, refer to PAINTTEXTBACKSTYLE. |
|
crBackgroundColor |
The COLORREF value that specifies the color to use for filling the text background when nBackgroundStyle is PAINT_TEXT_BACK_STYLE_OPAQUE. |
|
pBackgroundTileBitmap |
Pointer to the bitmap handle referencing the bitmap used to fill the text background when nBackgroundStyle is PAINT_TEXT_BACK_STYLE_TILEDIMAGE. The BITMAPHANDLE pointer should still be valid after setting this field. |
|
nAlignment |
An enumerated type that indicates text alignment. For a list of possible values, refer to PAINTALIGNMENT. |
|
nOpacity |
Value that indicates the transparency of the text when combined with the painting canvas. Valid values are 0 to 255. A color or an image with nOpacity of 255 is transparent. A color or an image with nOpacity of 0 is completely opaque (solid). |
|
|
||
pTexture |
Pointer to the bitmap handle referencing the bitmap that will simulate paper texture. Using a paper texture gives the appearance of painting on paper having that texture. The BITMAPHANDLE pointer should still be valid after setting this field. |
|
|
||
TransformInfo |
Structure that contains information used to transform the text output. |
|
|
The nRotate structure field of TransformInfo will effect the text output result only when the nAlignment field is: (PAINT_ALIGNMENT_HCENTER | PAINT_ALIGNMENT_VCENTER ) |
|
|
Otherwise, the toolkit will consider nRotate to be 0. |
