Demo - "Collapsible" sections of windows

This demo shows one techinique for creating a collapsible section (Column) within your window.
|
2020-08-04 16:14:50 +00:00
|
|
|
|
|
|
|
It uses the "pin" function so you'll need version 4.28.0+
|
|
|
|
|

|
|
|
A number of "shortcut aliases" are used in the layouts to compact things a bit.
|
|
|
|
In case you've not encountered these shortcuts, the meaning are:
|
|
|
|
B = Button, T = Text, I = Input = InputText, k = key
|
|
|
|
Also, both methods for specifying Button colors were used (tuple / single string)
|
|
|
|
Section #2 uses them the most to show you what it's like to use more compact names.
|
|
|
|
|
|
|
|
To open/close a section, click on the arrow or name of the section.
|
|
|
|
Section 2 can also be controlled using the checkbox at the top of the window just to
|
|
|
|
show that there are multiple way to trigger events such as these.
