PySide.QtGui.QFontInfo class provides general information about fonts.
PySide.QtGui.QFontInfo class provides the same access functions as PySide.QtGui.QFont ，如 PySide.QtGui.QFontInfo.family() , PySide.QtGui.QFontInfo.pointSize() , PySide.QtGui.QFontInfo.italic() , PySide.QtGui.QFontInfo.weight() , PySide.QtGui.QFontInfo.fixedPitch() , PySide.QtGui.QFontInfo.styleHint() etc. But whilst the PySide.QtGui.QFont access functions return the values that were set, a PySide.QtGui.QFontInfo object returns the values that apply to the font that will actually be used to draw the text.
For example, when the program asks for a 25pt Courier font on a machine that has a non-scalable 24pt Courier font, PySide.QtGui.QFont will (normally) use the 24pt Courier for rendering. In this case, QFont.pointSize() returns 25 and QFontInfo.pointSize() returns 24.
There are three ways to create a PySide.QtGui.QFontInfo 对象。
| 参数： | arg__1 – PySide.QtGui.QFont |
|---|
Constructs a font info object for font .
The font must be screen-compatible, i.e. a font you use when drawing text in widgets or pixmaps , not PySide.QtGui.QPicture or PySide.QtGui.QPrinter .
The font info object holds the information for the font that is passed in the constructor at the time it is created, and is not updated if the font's attributes are changed later.
使用 QPainter.fontInfo() to get the font info when painting. This will give correct results also when painting on paint device that is not screen-compatible.
