/* 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.

|
|
* an array or a callback to call to handle drawing the graph.
|
|
* For the immediate mode version you start by calling `nk_chart_begin`
|
|
* and need to provide min and max values for scaling on the Y-axis.
|
|
* and then call `nk_chart_push` to push values into the chart.
|
|
* Finally `nk_chart_end` needs to be called to end the process. */
