Note
Image accepts all transformations.
- Parameters
image_path (
Union
[str
,BaseImage
,Path
,BytesIO
]) – Path of the image, BytesIO object, orpygame_menu.baseimage.BaseImage
object. Ifpygame_menu.baseimage.BaseImage
object is provided drawing mode is not consideredimage_id (
str
) – Image IDangle (
Union
[int
,float
]) – Angle of the image in degrees (clockwise)onselect (
Optional
[Callable
]) – Function when selecting the widgetscale (

Adds a function to the Widget to be executed each time the widget is drawn.
The function that this method receives two objects: the Widget itself and the Menu reference.
import math def draw_update_function(widget, menu): t = widget.get_attribute('t', 0) t += menu.get_clock().get_time() widget.set_padding(10*(1 + math.sin(t))) # Oscillating padding button = menu.add.button('This button updates its padding', None) button.set_draw_callback(draw_update_function)
After creating a new callback, this functions returns the ID of the call. It can be removed anytime using
pygame_menu.widgets.core.widget.Widget.remove_draw_callback()
.Note
If Menu surface cache is enabled this method may run only once. To force running the added method each time call
widget.force_menu_surface_update()
to force Menu update the cache status if the drawing callback does not make the Widget to render. Remember that rendering the Widget forces the Menu to update its surface, thus updating the cache too.
Adds the Widget object to kwargs, it helps to get the Widget reference for callbacks. It raises
KeyError
if key is duplicated.
Adds a function to the Widget to be executed each time the Widget is updated.
The function that this method receives three objects: the events list, the Widget itself and the Menu reference. It is similar to
pygame_menu.widgets.core.widget.Widget.add_draw_callback()
.After creating a new callback, this functions returns the ID of the call. It can be removed anytime using
pygame_menu.widgets.core.widget.Widget.remove_update_callback()
.Note
Not all widgets are updated, so the provided function may never be executed in some widgets (for example, label or images).
Apply callbacks on Widget draw.
- Return type
- Returns
Self reference
Apply callbacks on Widget update.
Note
Readonly widgets or hidden widgets do not apply update callbacks.
Expand the Widget background inflate to match the selection effect (the Widget don’t require to be selected).
This is a permanent change; for dynamic purposes, depending on if the widget is selected or not, setting
widget.selection_expand_background
toTrue
may help.Note
This method may have unexpected results with certain selection effects.
- Return type
- Returns
Self reference
Draw the Widget on a given surface.
Note
Widget drawing order:
Background color
prev
decoratorWidget selection effect (if prev)
Widget surface
Widget selection effect (if post)
Widget border

decorator
Transformation: This method can flip the Widget either vertically, horizontally, or both. Flipping a Widget is non-destructive and does not change the dimensions.
Note
Flip is only applied after Widget rendering. Thus, the changes are not immediate.
Note
Use
pygame_menu.widgets.core.widget.Widget.render()
method to force Widget rendering after calling this method.
Forces menu surface cache to update after next drawing call. This also updates widget decoration.
Note
This method only updates the surface cache, without forcing re-rendering of all Menu widgets as
pygame_menu.widgets.core.widget.Widget.force_menu_surface_update()
does.- Return type
- Returns
Self reference
Forces menu surface update after next rendering call. This method automatically updates widget decoration cache as Menu render forces it to re-render.
This method also should be aclled by each widget after render.
Note
This method is expensive, as menu surface update forces re-rendering of all widgets (because them can change in size, position, etc…).

Public rendering method.
Note
Unlike private
_render
method, public method forces widget rendering (callingpygame_menu.widgets.core.widget.Widget._force_render()
). Use this method only if the widget has changed the state. Running this function many times may affect the performance.Note
Before rendering, check out if the widget font/title/values are set. If not, it is probable that a zero-size surface is set.
Transformation: Set the Widget size to another size.
Note
This method calls
pygame_menu.widgets.core.widget.Widget.scale()
method; thus, some widgets may not support this transformation.Note
The resize method uses the base Widget size, without any transformation, if a scaling factor is applied it unscales and then scales back to get the desired width/height.
Note
Resize is only applied after Widget rendering. Thus, the changes are not immediate.
Note
Use
pygame_menu.widgets.core.widget.Widget.render()
method to force widget rendering after calling this method.Warning
Final Widget size may not be exactly the same as the desired (width, height) tuple due to rounding errors, expect ±2 px average.
Transformation: Unfiltered counterclockwise rotation. The angle argument represents degrees and can be any floating point value. Negative angle amounts will rotate clockwise.
Note
Not all widgets accepts rotation. Also, this rotation only affects the text or images, the selection or background is not rotated.
Note
Rotation is only applied after widget rendering. Thus, the changes are not immediate.
Note
Use
pygame_menu.widgets.core.widget.Widget.render()
method to force widget rendering after calling this method.
Transformation: Scale the Widget to a desired width and height factor.
Note
Not all widgets are affected by scale.
Note
Scale considers widget padding.
Note
Scale is only applied after widget rendering. Thus, the changes are not immediate.
Note
Use
pygame_menu.widgets.core.widget.Widget.render()
method to force widget rendering after calling this method.Warning
Widget will scale only if
pygame_menu.widgets.core.widget.Widget.set_max_width()
andpygame_menu.widgets.core.widget.Widget.set_max_height()
are set toNone
. Thus, calling this method disables both max width and height.
The container ScrollArea scrolls to the Widget.
Mark the Widget as selected and execute the
onselect
callback function as follows:onselect(selected, widget, menu) <or> onselect()
If Widget
is_selectable
isFalse
this function is not executed.Note
Use
pygame_menu.widgets.core.widget.Widget.render()
method to force Widget rendering after calling this method.Warning
This method should only be used by the menu.
Set the alignment of the Widget.
Note
Alignment is only applied when updating the widget position, done by Menu when rendering the surface. Thus, the alignment change is not immediate.
Note
Use
pygame_menu.widgets.core.widget.Widget.render()
method to force widget rendering after calling this method.Note
See
pygame_menu.locals
for validalign
values.
Set an attribute.
Set the Widget background color.
- Parameters

- Return type
- Returns
Self reference
Set the (column, row, index) position. If the column or row is
-1
then the widget is not assigned to a certain column/row (for example, if it’s hidden).
Set a new controller object.
- Parameters
controller (
Controller
) – Controller- Return type
- Returns
Self reference
Enable interfaces to control the Widget.
Set the Widget cursor if user places the mouse over the Widget.
Set the floating status. If
True
the Widget don’t contribute its width/height to the Menu widget positioning computation (for example, the surface area or the column/row layout), and don’t add one unit to the rows (use the same vertical place as the previous widget).For example, before floating:
---------------------------- | wid1 | wid3 | | wid2 | wid4 | ----------------------------
After
wid3.set_float(True)
:---------------------------- | wid1 | wid4 | | wid2,wid3 | | ----------------------------
If the Widget is within a Frame, it does not contribute to the width/height of the layout. Also, it is being set to the (0, 0) position, thus, the only way to move the Widget to a desired position is by translating it.
- Parameters
- Return type
Set the
pygame_menu.baseimage.BaseImage
object from widget.
Set the Widget margin (left, bottom).
Transformation: Set the Widget max height, it applies a scaling factor if the widget height is greater than the limit.
Note
Max height considers padding.
Note
Max height is only applied after Widget rendering. Thus, the changes are not immediate.
Note
Use
pygame_menu.widgets.core.widget.Widget.render()
method to force widget rendering after calling this method.Warning
Final Widget size may not be exactly the same as the desired (width, height) tuple due to rounding errors, expect ±2 px average.
Warning
Widget will scale only if
pygame_menu.widgets.core.widget.Widget.scale()
andpygame_menu.widgets.core.widget.Widget.set_max_width()
are set toNone
. Thus, calling this method disables both scale and max width.
Transformation: Set the Widget max width, it applies a scaling factor if the widget width is greater than the limit.
Note
If
width=0
the widget will use the max column width of the Menu (using the column the widget belongs to).Note
Max width considers padding.
Note
Max width is only applied after widget rendering. Thus, the changes are not immediate.
Note
Use
pygame_menu.widgets.core.widget.Widget.render()
method to force widget rendering after calling this method.Warning
Final Widget size may not be exactly the same as the desired (width, height) tuple due to rounding errors, expect ±2 px average.
