PartitionSplitter: A (very custom) widget for easily splitting one existing partition into two.
Layout:
+--------------------+---------------+--------------------------+ | Old Partition | Old Partition | New Partition | | used | free | | +--------------------+---------------+--------------------------+ Old Partition free New Partition [ 123 ] ================O================================ [ 123 ]
At the top, there is a BarGraph that dynamicylla displays the sizes in graphical form. Below are an IntField to the left and an IntField to the right, each with its respective label. Between the two IntFields there is a Slider.
The user can enter a value in either IntField or drag the slider. The other sub-widgets (including the BarGraph) will automatically be adjusted. Visually (in the BarGraph), the border between "old partition free" and "new partition" will move left and right. The border between "old partition used" and "old partition free" is static.
There are built-in (configurable) limits for the minimum sizes of "old partition free" and "new partition".
