Description

A very specialized widget to allow a user to comfortably split an existing hard disk partition in two parts. Shows a bar graph that displays the used space of the partition, the remaining free space (before the split) of the partition and the space of the new partition (as suggested). Below the bar graph is a slider with an input fields to the left and right where the user can either input the desired remaining free space or the desired size of the new partition or drag the slider to do this.

The total size is usedSize+freeSize.

The user can resize the new partition between minNewPartSize and totalFreeSize-minFreeSize.

	Note
	This is a "special" widget, i.e. not all UIs necessarily support it. Check for availability with HasSpecialWidget( `PartitionSplitter ) before using it.

Usage

 	if ( HasSpecialWidget( `PartitionSplitter ) {...
 	`PartitionSplitter( 600, 1200, 800, 300, 50,
                                 "Windows used\n%1 MB", "Windows used\n%1 MB", "Linux\n%1 MB", "Linux ( MB )" )
