textChildAnchorNew

Create a new TextChildAnchor.

Using textBufferCreateChildAnchor is usually simpler then executing this function and textBufferInsertChildAnchor.

textViewNew

Create a new TextView widget with a default TextBuffer.

textChildAnchorGetDeleted

Query if an anchor was deleted.

textChildAnchorGetWidgets

Retrieve all Widgets at this TextChildAnchor.

The widgets in the returned list need to be upcasted to what they were.

textViewAddChildAtAnchor

Add a child widget in the TextBuffer at a given TextChildAnchor.

textViewAddChildInWindow

Place a widget in within the text.

This function places a Widget at an absolute pixel position into the TextView. Note that any scrolling will leave the widget in the same spot as it was.

The position x, y is relative to the DrawWindow specified by TextWindowType.

textViewBackwardDisplayLine

Move the iterator backwards by one display line.

See textViewForwardDisplayLine.

textViewBackwardDisplayLineEnd

Move the iterator backwards and to the end.

See textViewForwardDisplayLineEnd.

textViewBackwardDisplayLineStart

Move the iterator backwards and to the start.

See textViewForwardDisplayLineStart.

textViewBufferToWindowCoords

Convert buffer cooridnates into window coordinates.

textViewForwardDisplayLine

Move the iterator forwards by one display line.

Moves the given TextIter forward by one display (wrapped) line. A display line is different from a paragraph. Paragraphs are separated by newlines or other paragraph separator characters. Display lines are created by line-wrapping a paragraph. If wrapping is turned off, display lines and paragraphs will be the same. Display lines are divided differently for each view, since they depend on the view's width; paragraphs are the same in all views, since they depend on the contents of the TextBuffer.

textViewForwardDisplayLineEnd

Move the iterator forwards and to the end.

Like textViewForwardDisplayLine but moves to the end of the line as well.

textViewForwardDisplayLineStart

Move the iterator forwards and to the start.

Like textViewForwardDisplayLine but moves to the start of the line as well.

textViewGetBorderWindowSize

Retrieve the border width of the specified window.

See textViewSetBorderWindowSize.

textViewGetCursorVisible

Retrieve information whether the cursor in a TextView is visible or not.

textViewGetEditable

Retrieve information whether a TextView is editable or not.

textViewGetIndent

Get the indentation in pixels for the first line in a paragraph.

Tags in the buffer may override this default.

The indentation may be negative.

textViewGetIterAtLocation

Retrieves the TextIter at buffer coordinates x and y.

textViewGetIterLocation

Get a rectangle that roughly contains the character at TextIter.

Use textViewBufferToWindowCoords to convert into window cooridnates.

textViewGetJustification

Query how text is wrapped.

textViewGetLeftMargin

Get the number of pixels in the margin.

Tags in the buffer may override this default.

textViewGetLineAtY

Get the TextIter at the start of the line containing the coordinate y.

y is in buffer coordinates.

Returns the TextIter and the top of the line.

textViewGetLineYrange

Get the y coordinate of the top and the height of the line TextIter is on.

textViewGetPixelsAboveLines

Get the number of pixels above each paragraph.

Tags in the buffer may override this default.

textViewGetPixelsBelowLines

Get the number of pixels below each paragraph.

Tags in the buffer may override this default.

textViewGetPixelsInsideWrap

Get the number of pixels between lines inside a wraped paragraph.

Tags in the buffer may override this default.

textViewGetRightMargin

Get the number of pixels in the margin.

Tags in the buffer may override this default.

textViewGetVisibleRect

Get the currently visible rectangle.

Use textViewBufferToWindowCoords to convert into window coordinates.

textViewGetWindow

Get the underlying DrawWindow.

The TextWindowType determines which window of the TextWidget we would like to receive.

Returns Nothing if there is no DrawWindow of the specified type.

textViewGetWindowType

Retrieve the type of window the TextView widget contains.

Usually used to find out which window an event corresponds to. An emission of an event signal of TextView yields a DrawWindow. This function can be used to see if the event actually belongs to the main text window.

textViewGetWrapMode

Query how text is wrapped.

textViewMoveChild

Move a child widget within the TextView.

textViewMoveMarkOnscreen

Move a TextMark within the buffer until it is in the currently visible area of the widget.

Returns True if the Mark was moved.

textViewMoveVisually

Move the iterator a number of lines.

count is in display lines. See textViewForwardDisplayLine.

textViewNewWithBuffer

Create a new TextView widget with the given TextBuffer.

textViewPlaceCursorOnscreen

Move the cursor within the buffer until it is in the currently visible area of the widget.

Returns True if the Mark was moved.

textViewScrollMarkOnscreen

Scroll the visible area of the widget so the TextMark becomes visible.

This call is equivalent to textViewScrollToMark tm 0.0 Nothing tv.

textViewScrollToIter

Scroll to the position of the supplied TextIter.

The position might not be correct due to the delayed calculation of the line heights.

Returns True if the function actually scrolled.

textViewScrollToMark

Scroll to the position of the supplied TextMark.

Supplying xalign, yalign gives a goal position of the TextMark within screen bounds. 0,0 means left, top and 1.0,1.0 means right, bottom.

Supply Nothing if the goal is to bring the position into view with the minimum of scrolling.

withinMargin is within [0.0 .. 0.5) and imposes an extra margin at all four sides of the window within which xalign and yalign are evaluated.

The line distances are calculated in an idle handler. Calling this function ensures that the line heights are indeed evaluated before the scroll is carried out.

textViewSetBorderWindowSize

Set the border width of the TextView widget.

Sets the width of TextWindowLeft or TextWindowRight, or the height of TextWindowTop or TextWindowBottom. Automatically destroys the corresponding window if the size is set to 0 and creates the window if the size is set to non-zero. This function can only used with the four window types mentioned.

textViewSetBuffer

Set the TextBuffer for a given TextView widget.

textViewSetCursorVisible

Toggle whether the cursor in the TextView is visible or not.

textViewSetEditable

Toggle whether the text in the TextView is editable or not.

textViewSetIndent

Set the indentation in pixels for the first line in a paragraph.

Tags in the buffer may override this default.

The indentation may be negative.

textViewSetJustification

Specify how to wrap text.

textViewSetLeftMargin

Set the number of pixels in the margin.

Tags in the buffer may override this default.

textViewSetPixelsAboveLines

Set the number of pixels above each paragraph.

Tags in the buffer may override this default.

textViewSetPixelsBelowLines

Set the number of pixels below each paragraph.

Tags in the buffer may override this default.

textViewSetPixelsInsideWrap

Set the number of pixels between lines inside a wraped paragraph.

Tags in the buffer may override this default.

textViewSetRightMargin

Set the number of pixels in the margin.

Tags in the buffer may override this default.

textViewSetWrapMode

Specify how to wrap text.

textViewWindowToBufferCoords

Convert window cooridnates into buffer coordinates.

onCopyClipboard

Copying to the clipboard.

This signal is emitted when a selection is copied to the clipboard.

The action itself happens when the TextView processes this signal.

onCutClipboard

Cutting to the clipboard.

This signal is emitted when a selection is cut out and copied to the clipboard. The action itself happens when the textview processed this request.

onDeleteFromCursor

The widget will insert the string into the text where the meaning of units depends on the kind of deletion.

The action itself happens when the TextView processes this signal.

onMoveCursor

Moving the cursor.

The signal specifies what kind and how many steps the cursor will do. The flag is set to

True

if this movement extends a selection.

The action itself happens when the TextView processes this signal.

onMoveFocus

Moving the focus.

The action itself happens when the TextView processes this signal.

onPageHorizontally

Page change signals.

The signal specifies how many pages the view should move up or down. The flag is set to

True

if this movement extends a selection.
