sender()
senderSignalIndex()
setHeightSpinBox(self, widget: QDoubleSpinBox)

Registers a spin box widget as the linked “height” spin box.

If both a width and height spin box are linked to the button, they will automatically have their values updates when if the other spin box value is changed. I.e. changing the width spin box will automatically update the height spin box to a value which keeps the same locked ratio.

setLocked(self, locked: bool)

Sets whether the button state is locked.

Parameters

locked – locked state

setWidthSpinBox(self, widget: QDoubleSpinBox)

Registers a spin box widget as the linked “width” spin box.

If both a width and height spin box are linked to the button, they will automatically have their values updates when if the other spin box value is changed. I.e. changing the width spin box will automatically update the height spin box to a value which keeps the same locked ratio.
