Class API

class BasePyControl(wx.Control)

Base class used to hold common code for the HSB colour wheel and the RGB colour cube.

Methods

__init__(self, parent, bitmap=None)

Default class constructor. Used internally. Do not call it in your code!

Parameters:

• parent – the control parent;

• bitmap – the background bitmap for this custom control.

---

AcceptsFocus(self)

Can this window be given focus by mouse click?

---

AcceptsFocusFromKeyboard(self)

Can this window be given focus by keyboard navigation? If not, the only way to give it focus (provided it accepts it at all) is to click it.

Note

This method always returns False as we do not accept focus from the keyboard.

Note

Overridden from wx.Control.

---

DoGetBestSize(self)

Overridden base class virtual. Determines the best size of the control based on the bitmap size.

Note

Overridden from wx.Control.

---

DrawLines(self, dc)
