/* Combobox Widgets
* In this library comboboxes are not limited to being a popup
* list of selectable text. Instead it is a abstract concept of
* having something that is *selected* or displayed, a popup window
* which opens if something needs to be modified and the content
* of the popup which causes the *selected* or displayed value to
* change or if wanted close the combobox.
*
* While strange at first handling comboboxes in a abstract way
* solves the problem of overloaded window content. For example
* changing a color value requires 4 value modifier (slider, property,...)
* for RGBA then you need a label and ways to display the current color.
* If you want to go fancy you even add rgb and hsv ratio boxes.
* While fine for one color if you have a lot of them it because
* tedious to look at and quite wasteful in space. You could add
* a popup which modifies the color but this does not solve the
* fact that it still requires a lot of cluttered space to do.
*
* In these kind of instance abstract comboboxes are quite handy. All
* value modifiers are hidden inside the combobox popup and only
* the color is shown if not open. This combines the clarity of the
* popup with the ease of use of just using the space for modifiers.
*
* Other instances are for example time and especially date picker,
* which only show the currently activated time/data and hide the
* selection logic inside the combobox popup.
