|

|
|
* - `LUI_SLIDER_KNOB_TYPE_DEFAULT`: A rectangular knob.
|

|
|
* - `LUI_SLIDER_KNOB_TYPE_TEXT`: Text will be rendered in place of knob. This
|

|
|
* text can be value of progress bar, custom text, or both.
|

|

|

|

|
* <tt>buttongrid</tt> is a grid of buttons. It's way more effcient than adding

|
|
* buttons in a 5x4 grid, creating 20 individual button objects will take lots of

|
|
* RAM. Rather using a 5x4 buttongrid will only create a single object and saves
|
||
|
|
* RAM significantly.
|
||
|

* @brief API for <b><tt>panel</tt></b> widget
|
||
|
|
*
|
||
|
|
* A panel is just a container for multiple widgets (objects). This is used for
|
||
|
|
* grouping widgets together. Panels can act as parent widget and must have a
|
||
|
|
* scene as its parent.
|
||
|
|
*
|
||
|
|
* When widgets are added as children to a panel, their posions are relative to
|
||
|
|
* the panel. For example, assume a panel is at (X=10, Y=20) position relative to its
|
||
|
|
* parent scene. Now create a button and set the panel as its parent. Now, the position
|
||
|
|
* of the button will be realtive to the panel. Setting the button's position to
|
||
|
|
* (X=5, Y=3) means it global position actually is (X=15, Y=23).
|
||
|
|
*
|
||
|
|
* Moving a panel to a new position also moves all its children with it. Making a panel
|
||
|
|
* hidden also hides all its children with it. Scaling a panel does NOT scales its
|
||
|
|
* children. But if the new scale is too small to contain all its children, render
|
||
|
|
* result will be unpredictable.
|
||
|
|
*
|
||
|
|
* @note A panel can have layout. All children under the panel will follow the layout. When layout
|
||
|
|
* is enabled, children's position is set by that layout. Currently only horizontal and vertical layouts are supported.
