DCFontChanger is a small helper class for setting a font on a DC and unsetting it automatically in the destructor, restoring the previous one.

### Methods¶

__init__(self, *args, **kw)

__init__ (self, dc)

Trivial constructor not changing anything.

This constructor is useful if you don’t know beforehand if the font needs to be changed or not. It simply creates the object which won’t do anything in its destructor unless Set is called – in which case it would reset the previous font.

Parameters

dc (wx.DC) –

New in version 2.9.1.

__init__ (self, dc, font)

Sets font on the given dc, storing the old one.

Parameters
• dc (wx.DC) – The DC where the font must be temporary set.

• font (wx.Font) – The font to set.

Set(self, font)

Set the font to use.

This method is meant to be called once only and only on the objects created with the constructor overload not taking wx.Font argument and has the same effect as the other constructor, i.e. sets the font to the given font and ensures that the old value is restored when this object is destroyed.

Parameters

font (wx.Font) –

__enter__(self)

__exit__(self, exc_type, exc_val, exc_tb)
