1 '''
2 onoffbutton.py
3
4 A custom class On/Off clickable - meant as a replacement for CheckBox.
5
6 Events: EVT_ON_OFF Generic event on binary change
7
8 EVT_ON The control changed to On
9
10 EVT_OFF The control changed to Off
11
12 Event Notes:
13 All events return GetValue() and GetId() i.e.
14
15 def OnOff(self, event):
16 current_value = event.GetValue()
17 id = event.GetId()
18
19 Functions:
20 GetValue() Returns numeric value in the control On (True) = 1 Off (False) = 0
21 SetValue(int) Set numeric value in the control
22 GetId() Get widget Id
23 GetLabel() Get current label for the control
24 SetLabel(str) Set label for the control
25 SetToolTip(str) Set tooltip for the control
26 SetForegroundColour Set text colour
27 SetBackgroundColour Set background colour
28 SetOnColour Set On background colour
29 SetOnForegroundColour Set On foreground colour
30 SetOffColour Set Off background colour
31 SetOffForegroundColour Set Off foreground colour
32 SetFont(font) Set label font
33 GetFont() Get label font
34 Enable(Bool) Enable/Disable the control
35 IsEnabled() Is the control Enabled - Returns True/False
36 SetSpacing(int) Set size of space between control and label
37 GetSpacing() Get size of space between control and label
38
39 Default Values:
40 initial - 0 (False) Off
41 label - blank
42 style - wx.BORDER_NONE
43 mono - False
44 border - True
45 size - 24x16 (Almost as small as a CheckBox)
46 circle - True
47 internal_style - OOB_CIRCLE = 0
48
49 The control is either a rounded rectangle or a rectangle, controlled by the parameter, circle
50 The internal style indicator which shows the controls position, On or Off, can be a circle, an arrow
51 a rectangle or a sized radio button, the default is a circle
52 Choosing a rectangle forces the control to be a rectangular shape
53 Choosing Radio forces the control to look like a radio button
54
55 Tooltips are either [On] or [Off] unless a tooltip has been set, in which case [Currently On] or
56 [Currently Off] is added to the existing tooltip
57
58 Valid control styles:
59 Window border styles e.g. wx.BORDER_NONE, wx.BORDER_SIMPLE etc
60 wx.ALIGN_RIGHT Align control to the Right of the Label
61
62 Valid internal styles:
63 OOB_CIRCLE = 0
64 OOB_ARROW = 1
65 OOB_RECTANGLE = 2
66 OOB_RADIO = 3

72 Version: 1.15.4
73 Email: <rolfofsaxony@gmx.com>
74 Written & tested: Linux, Python 3.8.10
75
76 Change Log:
77 1.15.4 Minor, mainly cosmetic, adjustments
78 Function Enable defaults to True
79 Add function Disable defaulting to False
80
81 1.15.3 Rectangular radio box internal indicator is now a square
82 Control's text forced to system disabled grey and italic when disabled
83
84 1.15.2 Radio dimensions are forced to be an odd value, as this centres better within the outer border
85 Disabled image bitmap.ConvertToDisabled() not satisfactory, now built specifically again
86
87 1.15.1 Label and Spacing are hidden if not present, to prevent the control displaying larger than necessary
88 This becomes more obvious if someone is using gradient colours for panel backgrounds
89
90 1.15.0 Adds sized Radio button style
91 Rationalise internal style (arrow, rect) to a single variable 'internal_style'
92 Values:
93 OOB_CIRCLE = 0 Default
94 OOB_ARROW = 1
95 OOB_RECTANGLE = 2
96 OOB_RADIO = 3
97
98 1.14.0 Rectangle control indicator re-introduced via rect parameter
99 Control's text forced to dim grey when disabled
100
101 1.13.0 Choice between Circle and Arrow Head for the control's indicator
102 The left click Toggle is bound to both the Label and the control.
103 As this widget is envisaged to be used for very small on/off controls,
104 it is easier to toggle if the Bind includes the Label
105 Add a small border width, left or right as appropriate, to the Label
106 Utilise wx.Bitmap's ConvertToDisabled() function for disabled bitmaps
107
108 1.12.3 Change allows for the recognition of mnemonics, allowing an
109 Alt key + a letter key, to toggle the button, when the letter is preceded
110 by an ampersand (&), in the widgets label e.g- ("&Go") Alt+G
111 Fixes for python3 10+ differences
112 Colours revert to #xxxxxx rather than colour names, as MS Windows reportedly struggles with names
113 Text sizing is performed using a DC, not calculated from pixel size
114 Disabled button is specifically set as MS Windows reportedly does not change the image with the control
115 Disabled bitmaps now created for Disabled On and Disabled Off to cater for the above
116
117 1.11.0 Changes rectangular button to have a Circular on/off widget
118 This makes whether the button is on or off clearer
119 especially if it is Mono colour
120
121 1.10.0 Adds
122 SetOnForegroundColour function
123 SetOffForegroundColour function
124 Default Off background colour changed from red to grey
125
126 1.9.0 Adds
127 SetOnColour function
128 SetOffColour function
129
130 1.8.0 Adds
131 rectangle style On/Off control
132 SetSpacing function
133 Align Right style
134
135 1.7.0 First real release
136
