class SButton(wx.Window)

This is the main implementation of ShapedButton.


Methods

__init__(self, parent, id=wx.ID_ANY, label='', pos=wx.DefaultPosition, size=wx.DefaultSize)

Default class constructor.

Parameters:

  • parent – the SButton parent. Must not be None;

  • id – window identifier. A value of -1 indicates a default value;

  • 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.


AcceptsFocus(self)

Note

Overridden from wx.Window.


ConvertPILToWX(self, pil, alpha=True)

Note

Overridden from wx.Window.


DrawFocusIndicator(self, dc, width, height)

Draws the focus indicator. This is a circle/ellipse inside the button drawn with a dotted-style pen, to let the user know which button has the focus.

Parameters:

  • dc – an instance of wx.DC;

  • width – the button width;

  • height – the button height.


DrawLabel(self, dc, width, height, dw=0, dh=0)

Draws the label on the button.

Parameters:

  • dc – an instance of wx.DC;

  • width – the button width;

  • height – the button height;

  • dw – width differential, to show a 3D effect;

  • dh – height differential, to show a 3D effect.


DrawMainButton(self, dc, width, height)

Draws the main button, in whichever state it is.

Parameters:

  • dc – an instance of wx.DC;

  • width – the button width;

  • height – the button height.


Enable(self, enable=True)

Enables/disables the button.

Parameters:

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

Note

Overridden from wx.Window.


GetAngleOfRotation(self)

Returns angle of button label rotation, in degrees.


GetButtonColour(self)

Returns the button colour.


GetEllipseAxis(self)

Returns the ellipse axes.


GetLabel(self)

Returns the button label.


GetLabelColour(self)

GetUseFocusIndicator(self)

Returns focus indicator flag.


InitColours(self)

Calculates a new set of focus indicator colour and indicator pen based on button colour and label colour.


IsEnabled(self)

Returns whether the button is enabled or not.


IsOutside(self, x, y)

Checks if a mouse events occurred inside the circle/ellipse or not.

Parameters:

  • x – the mouse x position;

  • y – the mouse y position.


MakePalette(self, tr, tg, tb)

Creates a palette to be applied on an image based on input colour.

Parameters:

Parameters:

event – a KeyEvent event to be processed.


OnKeyUp(self, event)

Handles the wx.EVT_KEY_UP event for SButton.

Parameters:

event – a KeyEvent event to be processed.


OnLeftDown(self, event)

Handles the wx.EVT_LEFT_DOWN event for SButton.

Parameters:

event – a MouseEvent event to be processed.


OnLoseFocus(self, event)

event – a FocusEvent event to be processed.


OnMotion(self, event)

Handles the wx.EVT_MOTION event for SButton.

Parameters:

event – a MouseEvent event to be processed.


OnPaint(self, event)

Handles the wx.EVT_PAINT event for SButton.

Parameters:

event – a PaintEvent event to be processed.


OnSize(self, event)

Handles the wx.EVT_SIZE event for SButton.

event – a wx.SizeEvent event to be processed.


SetAngleOfRotation(self, angle=None)

Sets angle of button label rotation.

Parameters:

angle – the label rotation, in degrees.


SetBestSize(self, size=None)

Given the current font settings, calculate and set a good size.

Parameters:

size – if not None, an instance of wx.Size to pass to SetInitialSize.


SetButtonColour(self, colour=None)

Sets the button colour, for all button states.

Parameters:

colour – an instance of wx.Colour.

Note

The original button images are greyscale with a lot of pixels with different colours. Changing smoothly the button colour in order to give the same 3D effect can be efficiently done only with PIL.


SetDefault(self)

Sets the button as default item.


SetEllipseAxis(self, main=None, secondary=None)

Sets the ellipse axis. What it is important is not their absolute values but their ratio.

Parameters:

  • main – a floating point number representing the absolute dimension of the main ellipse axis;

  • secondary – a floating point number representing the absolute dimension of the secondary ellipse axis.


SetLabel(self, label=None)

Sets the button label.

Parameters:

label – the new button label.


SetLabelColour(self, colour=None)

Parameters:

colour – an instance of wx.Colour.


SetUseFocusIndicator(self, flag)

Parameters:

flag – True to use the focus indicator, False otherwise.


ShouldInheritColours(self)
