Class API

class GradientButton(wx.PyControl)

This is the main class implementation of GradientButton.

---

__init__(parent, id=wx.ID_ANY, bitmap=None, label="", pos=wx.DefaultPosition, size=wx.DefaultSize, style=wx.NO_BORDER, validator=wx.DefaultValidator, name="gradientbutton")

Default class constructor.

Parameters:

• parent – the GradientButton parent;
• id – window identifier. A value of -1 indicates a default value;
• bitmap – the button bitmap (if any);
• label – the button text label;
• pos – the control position. A value of (-1, -1) indicates a default position, chosen by either the windowing system or wxPython, depending on platform;
• size – the control size. A value of (-1, -1) indicates a default size, chosen by either the windowing system or wxPython, depending on platform;
• style – the button style (unused);
• validator – the validator associated to the button;
• name – the button name.

---

AcceptsFocus()

Can this window be given focus by mouse click?

Note

Overridden from wx.PyControl.

---

DoGetBestSize()

Overridden base class virtual. Determines the best size of the button based on the label and bezel size.

Note

Overridden from wx.PyControl.

---

Enable(enable=True)

Enables/disables the button.

Parameters:enable – True to enable the button, False to disable it.

Note

Overridden from wx.PyControl.

---

GetBottomEndColour()

Returns the bottom end colour for the gradient shading.

---

GetBottomStartColour()

Returns the bottom start colour for the gradient shading.

---

GetDefaultAttributes()

Overridden base class virtual. By default we should use the same font/colour attributes as the native wx.Button.

---

GetPath(gc, rc, r)

Returns a rounded wx.GraphicsPath rectangle.

Parameters:

• gc – an instance of wx.GraphicsContext;
• rc – a client rectangle;
• r – the radious of the rounded part of the rectangle.

---

GetPressedBottomColour()

Returns the pressed bottom start colour for the gradient shading.

---

GetPressedTopColour()

Returns the pressed top start colour for the gradient shading.

---

GetTopEndColour()

Returns the top end colour for the gradient shading.

---

GetTopStartColour()

Returns the top start colour for the gradient shading.

---

LightColour(colour, percent)

Return light contrast of colour. The colour returned is from the scale of colour ==> white.

Parameters:

• colour – the input colour to be brightened;
• percent – determines how light the colour will be. percent = 100 returns white, percent = 0 returns colour.

---

---

OnLeftUp(event)

Handles the wx.EVT_LEFT_UP event for GradientButton.

Parameters:event – a wx.MouseEvent event to be processed.

---

OnLoseFocus(event)

Handles the wx.EVT_KILL_FOCUS event for GradientButton.

Parameters:event – a wx.FocusEvent event to be processed.

---

OnMouseEnter(event)

Handles the wx.EVT_ENTER_WINDOW event for GradientButton.

---

OnPaint(event)

Handles the wx.EVT_PAINT event for GradientButton.

Parameters:event – a wx.PaintEvent event to be processed.

---

OnSize(event)

Handles the wx.EVT_SIZE event for GradientButton.

Parameters:event – a wx.SizeEvent event to be processed.

---
