wx.SpinCtrl¶
wx.SpinCtrl combines wx.TextCtrl and wx.SpinButton in one control.
Window Styles¶
This class supports the following styles:
wx.SP_ARROW_KEYS
: The user can use arrow keys to change the value.wx.SP_WRAP
: The value wraps at the minimum and maximum.wx.TE_PROCESS_ENTER
: Indicates that the control should generatewxEVT_TEXT_ENTER
events. Using this style will prevent the user from using the Enter key for dialog navigation (e.g. activating the default button in the dialog) under MSW.wx.ALIGN_LEFT
: Same aswx.TE_LEFT
for wx.TextCtrl: the text is left aligned (this is the default).wx.ALIGN_CENTRE_HORIZONTAL
: Same aswx.TE_CENTRE
for wx.TextCtrl: the text is centered.wx.ALIGN_RIGHT
: Same aswx.TE_RIGHT
for wx.TextCtrl: the text is right aligned.
Events Emitted by this Class¶
Handlers bound for the following event types will receive a wx.SpinEvent parameter.
EVT_SPINCTRL: Process a wxEVT_SPINCTRL event, which is generated whenever the numeric value of the spin control is updated.
You may also use the
wx.SpinButton event macros, however the corresponding events will not be generated under all platforms. Finally, if the user modifies the text in the edit part of the spin control directly, the EVT_TEXT
is generated, like for the wx.TextCtrl. When the use enters text into the text area, the text is not validated until the control loses focus (e.g. by using the TAB
key). The value is then adjusted to the range and a wx.SpinEvent sent then if the value is different from the last value sent.

Class API¶
- class wx.SpinCtrl(Control)¶
Possible constructors:
SpinCtrl() -> None SpinCtrl(parent, id=ID_ANY, value='', pos=DefaultPosition, size=DefaultSize, style=SP_ARROW_KEYS, min=0, max=100, initial=0, name="wxSpinCtrl") -> None
SpinCtrl combines TextCtrl and SpinButton in one control.
Methods¶
- __init__(self, *args, **kw)¶
-
__init__ (self)
Default constructor.
- Return type:
None
__init__ (self, parent, id=ID_ANY, value=’’, pos=DefaultPosition, size=DefaultSize, style=SP_ARROW_KEYS, min=0, max=100, initial=0, name=”wxSpinCtrl”)
Constructor, creating and showing a spin control.
If value is non-empty, it will be shown in the text entry part of the control and if it has numeric value, the initial numeric value of the control, as returned by
GetValue
will also be determined by it instead of by initial. Hence, it only makes sense to specify initial if value is an empty string or is not convertible to a number, otherwise initial is simply ignored and the number specified by value is used.- Parameters:
parent (wx.Window) – Parent window. Must not be
None
.id (wx.WindowID) – Window identifier. The value
wx.ID_ANY
indicates a default value.value (string) – Default value (as text).
pos (wx.Point) – Window position. If
wx.DefaultPosition
is specified then a default position is chosen.size (wx.Size) – Window size. If
wx.DefaultSize
is specified then a default size is chosen.style (long) – Window style. See wx.SpinButton.
min (int) – Minimal value.
max (int) – Maximal value.
initial (int) – Initial value.
name (string) – Window name.
- Return type:
None

- Create(self, parent, id=ID_ANY, value='', pos=DefaultPosition, size=DefaultSize, style=SP_ARROW_KEYS, min=0, max=100, initial=0, name='wxSpinCtrl')¶
Creation function called by the spin control constructor.
See wx.SpinCtrl for details.
- GetBase(self)¶
Returns the numerical base being currently used, 10 by default.
- Return type:
int
Added in version 2.9.5.
See also
- static GetClassDefaultAttributes(variant=WINDOW_VARIANT_NORMAL)¶
- Parameters:
variant (WindowVariant)
- Return type:
- GetIncrement(self)¶
Get the value for increment for a spin control.
The default value is 1 but it can be changed using
SetIncrement
.- Return type:
int
Added in version 4.1/wxWidgets-3.1.6.
- GetMax(self)¶
Gets maximal allowable value.
- Return type:
int
- GetMin(self)¶
Gets minimal allowable value.
- Return type:
int
- GetRange(self)¶
- GetTextValue(self)¶
Returns the text in the text entry part of the control.
- Return type:
str
Added in version 4.1/wxWidgets-3.1.6.
- GetValue(self)¶
Gets the value of the spin control.
- Return type:
int
- SetBase(self, base)¶
Sets the base to use for the numbers in this control.
Currently the only supported values are 10 (which is the default) and 16.
Changing the base allows the user to enter the numbers in the specified base, e.g. with “0x” prefix for hexadecimal numbers, and also displays the numbers in the specified base when they are changed using the spin control arrows.
- Parameters:
base (int) – Numeric base, currently only 10 and 16 are supported.
- Return type:
bool
- Returns:
True
if the base was successfully changed orFalse
if it failed, usually meaning that either the base is not 10 or 16 or that the base is not supported for values in the current range.
Added in version 2.9.5.
Note
Setting a base to 16 is allowed only if current range does not include negative values.
- SetIncrement(self, value)¶
Sets the increment for the control.
The increment is the number by which the value changes when the up or down arrow is used.
The default is 1, but it can be useful to set it to a higher value when using the control for bigger numbers.
Note that it is still possible to enter any value (in the valid range) into the control manually, whatever is the value of the increment.
- Parameters:
value (int)
- Return type:
None
Added in version 4.1/wxWidgets-3.1.6.
- SetMax(self, maxVal)¶
- SetMin(self, minVal)¶
- SetRange(self, minVal, maxVal)¶
Sets range of allowable values.
Notice that calling this method may change the value of the control if it’s not inside the new valid range, e.g. it will become minVal if it is less than it now. However no
wxEVT_SPINCTRL
event is generated, even if it the value does change.- Parameters:
minVal (int)
maxVal (int)
- Return type:
None
Note
Setting a range including negative values is silently ignored if current base is set to 16.
- SetSelection(self, from_, to_)¶
Select the text in the text part of the control between positions from (inclusive) and to (exclusive).
This is similar to
wx.TextCtrl.SetSelection
.- Parameters:
from_ (long)
to_ (long)
- Return type:
None
Note
this is currently only implemented for Windows and generic versions of the control.
- SetValue(self, *args, **kw)¶
-
SetValue (self, text)
Sets the value of the spin control.
It is recommended to use the overload taking an integer value instead. If text doesn’t represent a valid number, it may not be shown in the text part of the control at all (only empty string is guaranteed to be supported under all platforms) and the numeric value will be changed to
GetMin
.Notice that, unlike
wx.TextCtrl.SetValue
, but like most of the other setter methods in wxWidgets, calling this method does not generate any events as events are only generated for the user actions.- Parameters:
text (string)
- Return type:
None
SetValue (self, value)
Sets the value of the spin control.
Calling this method doesn’t generate any
wxEVT_SPINCTRL
events.- Parameters:
value (int)
- Return type:
None
