new

viewNew

Arguments

:: (HasCallStack, MonadIO m)

=> m View

Returns: a new View.

Creates a new View.

By default, an empty Buffer will be lazily created and can be retrieved with textViewGetBuffer.

If you want to specify your own buffer, either override the TextViewClass create_buffer factory method, or use viewNewWithBuffer.

setBackgroundPattern

viewSetBackgroundPattern

Arguments

:: (HasCallStack, MonadIO m, IsView a)

=> a

view: a View.

-> BackgroundPatternType

backgroundPattern: the BackgroundPatternType.

-> m ()

Set if and how the background pattern should be displayed.

Since: 3.16

setDrawSpaces

viewSetDrawSpaces

Arguments

:: (HasCallStack, MonadIO m, IsView a)

=> a

view: a View.

-> [DrawSpacesFlags]

flags: DrawSpacesFlags specifing how white spaces should be displayed

-> m ()

Deprecated: (Since version 3.24)Use spaceDrawerSetTypesForLocationsinstead.

Set if and how the spaces should be visualized. Specifying flags as 0 will disable display of spaces.

For a finer-grained method, there is also the GtkSourceTag's Tag:draw-spaces property.

setHighlightCurrentLine

viewSetHighlightCurrentLine

Arguments

:: (HasCallStack, MonadIO m, IsView a)

=> a

view: a View.

-> Bool

highlight: whether to highlight the current line.

-> m ()

If highlight is True the current line will be highlighted.

setIndentOnTab

viewSetIndentOnTab

Arguments

:: (HasCallStack, MonadIO m, IsView a)

=> a

view: a View.

-> Bool

enable: whether to indent a block when tab is pressed.

-> m ()

If True, when the tab key is pressed when several lines are selected, the selected lines are indented of one level instead of being replaced with a \t character. Shift+Tab unindents the selection.

If the first or last line is not selected completely, it is also indented or unindented.

When the selection doesn't span several lines, the tab key always replaces the selection with a normal \t character.

setIndentWidth

viewSetIndentWidth

Arguments

:: (HasCallStack, MonadIO m, IsView a)

=> a

view: a View.

-> Int32

width: indent width in characters.

-> m ()

Sets the number of spaces to use for each step of indent when the tab key is pressed. If width is -1, the value of the View:tab-width property will be used.

The View:indent-width interacts with the View:insert-spaces-instead-of-tabs property and View:tab-width. An example will be clearer: if the View:indent-width is 4 and View:tab-width is 8 and View:insert-spaces-instead-of-tabs is False, then pressing the tab key at the beginning of a line will insert 4 spaces. So far so good. Pressing the tab key a second time will remove the 4 spaces and insert a \t character instead (since View:tab-width is 8). On the other hand, if View:insert-spaces-instead-of-tabs is True, the second tab key pressed will insert 4 more spaces for a total of 8 spaces in the TextBuffer.

The test-widget program (available in the GtkSourceView repository) may be useful to better understand the indentation settings (enable the space drawing!).

setInsertSpacesInsteadOfTabs

viewSetInsertSpacesInsteadOfTabs

Arguments

:: (HasCallStack, MonadIO m, IsView a)

=> a

view: a View.

-> Bool

enable: whether to insert spaces instead of tabs.

-> m ()

If True a tab key pressed is replaced by a group of space characters. Of course it is still possible to insert a real \t programmatically with the TextBuffer API.

:: (HasCallStack, MonadIO m, IsView a, IsMarkAttributes b)

=> a

view: a View.

-> Text

category: the category.

-> b

moveLines

type C_ViewMoveLinesCallback = Ptr () -> CInt -> Int32 -> Ptr () -> IO ()

Type for the callback on the (unwrapped) C side.

type ViewMoveLinesCallback

Arguments

 = Bool

copy: True if the line should be copied, False if it should be moved. This parameter is deprecated and will be removed in a later version, it should be always False.

-> Int32

count: the number of lines to move over. Only 1 and -1 are supported.

-> IO ()

The ::move-lines signal is a keybinding which gets emitted when the user initiates moving a line. The default binding key is Alt+Up/Down arrow. And moves the currently selected lines, or the current line by count. For the moment, only count of -1 or 1 is valid.

The copy parameter is deprecated, it has never been used by GtkSourceView (the value is always False) and was buggy.
