Overloaded Implementations:

__init__ (self, dc)

Trivial constructor not changing anything.

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

Parameters:dc (wx.DC) –

---

__init__ (self, dc, col)

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

Parameters:

• dc (wx.DC) – The DC where the colour must be temporary set.
• col (wx.Colour) – The colour to set.

---

---

Set(self, col)

Set the colour to use.

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

Parameters:col (wx.Colour) –
