static

Sorting comparator function for ExplorerEntry list items.

Parameters

a	LHS element.
b	RHS element.

Returns

Relative ordering value.

ExplorerGoUp()

static void ExplorerGoUp ( void  )

static

Navigates the current file explorer path up to its parent folder.

ExplorerNavigateTo()

static void ExplorerNavigateTo ( const char *  subdir )

static

Navigates the current file explorer path down into a subfolder.

Parameters

subdir

Target directory name.

Gc()

static GrColor Gc ( unsigned char  r, unsigned char  g, unsigned char  b, unsigned char  a  )

static

Constructs a GrColor value.

Parameters

r	Red channel.
