Methods

Overloaded methods

copy

tabArrayCopy Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> TabArray

src: TabArray to copy

-> m TabArray

Returns: the newly allocated TabArray, which should be freed with tabArrayFree.

Copies a TabArray

free

tabArrayFree Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> TabArray

tabArray: a TabArray

-> m () 

Frees a tab array and associated resources.

getPositionsInPixels

tabArrayGetPositionsInPixels Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> TabArray

tabArray: a TabArray

-> m Bool

Returns: whether positions are in pixels.

Returns True if the tab positions are in pixels, False if they are in Pango units.

getSize

tabArrayGetSize Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> TabArray

tabArray: a TabArray

-> m Int32

Returns: the number of tab stops in the array.

Gets the number of tab stops in tabArray.

getTab

tabArrayGetTab Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> TabArray

tabArray: a TabArray

-> Int32

tabIndex: tab stop index

-> m (TabAlign, Int32) 

Gets the alignment and position of a tab stop.

new

tabArrayNew Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> Int32

initialSize: Initial number of tab stops to allocate, can be 0

-> Bool

positionsInPixels: whether positions are in pixel units

-> m TabArray

Returns: the newly allocated TabArray, which should be freed with tabArrayFree.

Creates an array of initialSize tab stops. Tab stops are specified in pixel units if positionsInPixels is True, otherwise in Pango units. All stops are initially at position 0.

resize

tabArrayResize Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> TabArray

tabArray: a TabArray

-> Int32

newSize: new size of the array

-> m () 

Resizes a tab array. You must subsequently initialize any tabs that were added as a result of growing the array.

setTab

tabArraySetTab Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> TabArray

tabArray: a TabArray

-> Int32

tabIndex: the index of a tab stop

-> TabAlign

alignment: tab alignment

-> Int32

location: tab location in Pango units

-> m () 

Sets the alignment and location of a tab stop. alignment must always be PANGO_TAB_LEFT in the current implementation.
