wtext¶
The wtext object (widget text) is often used together with widgets such as sliders. It provides a way to modify dynamically a portion of the title or caption of a canvas, perhaps in response to user interactions or computed changes.
The example program ButtonsMenusSliders uses wtext to display the current rotation speed of a cube whose rotation is controlled by a slider.
Variables must be converted to a string using standard Python formatting options. Text may be updated any time by setting the text attribute of the wtext object:
myspeedtxt.text = f'omega = {vslider.value:.1e} radians/s'
