gtk.CellRenderer Properties

"alignment"	Read/Write	Specifies how to align the lines of text using one of the Pango Alignment Constants Default value: `pango.ALIGN_LEFT`. Note that you probably need the 'xalign' property of `gtk.CellRenderer` if you want to set the horizontal alignment of the whole text. This property is available in GTK+ 2.10 and above.
"attributes"	Read/Write	A list of style attributes to apply to the text of the renderer.
"background"	Write	Background color as a string. Default: `None`
"background-gdk"	Read/Write	Background color as a gtk.gdk.Color
"background-set"	Read/Write	If `True` this tag affects the background color. Default: `False`
"editable"	Read/Write	If `True` the text can be modified by the user. GTK+ 2.4 and above. Default: `False`
"editable-set"	Read/Write	If `True` this tag affects the text editability. GTK+ 2.4 and above. Default: `False`
"ellipsize"	Read/Write	The preferred place to ellipsize the string, if the cell renderer does not have enough room to display the entire string, if at all. GTK+ 2.6 and above. Default: `pango.ELLIPSIZE_NONE`
"ellipsize-set"	Read/Write	If `True` this tag affects the text editability. Default: `False`
"family"	Read/Write	Name of the font family, e.g. Sans, Helvetica, Times, Monospace. Default: `None`
"family-set"	Read/Write	If `True` this tag affects the font family. Default: `False`
"font"	Read/Write	Font description as a string. Default: `None`
"font-desc"	Read/Write	Font description as a `pango.FontDescription`
"foreground"	Write	Foreground color as a string. Default: `None`
"foreground-gdk"	Read/Write	Foreground color as a `gtk.gdk.Color`
"foreground-set"	Read/Write	If `True` this tag affects the foreground color. Default: `False`
"language"	Read/Write	The language this text is in, as an ISO code. Pango can use this as a hint when rendering the text. If you don't understand this parameter, you probably don't need it. GTK+ 2.4 and above. Default: `None`
"language-set"	Read/Write	If `True` this tag affects the language used to render the text. GTK+ 2.4 and above. Default: `False`
"markup"	Write	Marked up text to render. Default: `None`
"rise"	Read/Write	Offset of text above the baseline (below the baseline if rise is negative). Default: 0
"rise-set"	Read/Write	If `True` this tag affects the rise. Default: `False`
"scale"	Read/Write	Font scaling factor. Allowed values >= 0. Default: 1
"scale-set"	Read/Write	If `True` this tag scales the font. Default: `False`
"single-paragraph-mode"	Read/Write	If `True`, keep all text in a single paragraph. GTK+ 2.4 and above. Default: `False`
"size"	Read/Write	Font size. Allowed values >= 0. Default: 0
"size-points"	Read/Write	Font size in points. Allowed values >= 0. Default: 0
"size-set"	Read/Write	If `True` this tag affects the font size. Default: `False`
"stretch"	Read/Write	Font stretch. Default: `pango.STRETCH_NORMAL`
"stretch-set"	Read/Write	If `True` this tag affects the font stretch. Default: `False`
"strikethrough"	Read/Write	If `True` strike through the text. Default: `False`
"strikethrough-set"	Read/Write	If `True` this tag affects the strikethrough. Default: `False`
"style"	Read/Write	Font style. Default: `pango.STYLE_NORMAL`
"style-set"	Read/Write	If `True` this tag affects the font style. Default: `False`
"text"	Read/Write	Text to render. Default: `None`
"underline"	Read/Write	Style of underline for this text. Default: `pango.UNDERLINE_NONE`
"underline-set"	Read/Write	If `True` this tag affects the text underlining. Default: `False`
"variant"	Read/Write	Font variant. Default: `pango.VARIANT_NORMAL`
"variant-set"	Read/Write	If `True` this tag affects the font variant. Default: `False`
"weight"	Read/Write	Font weight. Allowed values >= 0. Default value: 400
"weight-set"	Read/Write	If `True` this tag affects the font weight. Default: `False`
"width-chars"	Read/Write	The desired width of the cell, in characters. If this property is set to -1, the width will be calculated automatically, otherwise the cell will request either 3 characters or the property value, whichever is greater. GTK+ 2.6 and above. Allowed values >= -1. Default value: -1
"wrap-mode"	Read-Write	Specifies how to break the string into multiple lines, if the cell renderer does not have enough room to display the entire string. This property has no effect unless the "wrap-width" property is set. This property is available in GTK+ 2.8 and above.
"wrap-width"	Read-Write	Specifies the width at which the text is wrapped. The "wrap-mode" property can be used to influence at what character positions the line breaks can be placed. Setting "wrap-width" to -1 turns wrapping off. This property is available in GTK+ 2.8 and above.

gtk.CellRendererText Signal Prototypes

"edited"

def callback(cellrenderertext, path, new_text, user_param1, ...)

Description

The gtk.CellRendererText manages the rendering of text into a gtk.TreeView cell, using the font, color and style information provided by its properties. The text will be ellipsized if it is too long and the "ellipsize" property allows it.

Constructor

    gtk.CellRendererText()

Returns :

the new cell renderer

Creates a new gtk.CellRendererText. The way that text is drawn is changed using object properties. The object properties can be set globally (with set_property()). Also, with gtk.TreeViewColumn, you can bind a property to a value in a gtk.TreeModel. For example, you can bind the "text" property on the cell renderer to a string value in the model, thus rendering a different string in each row of the gtk.TreeView.

Methods

gtk.CellRendererText.set_fixed_height_from_font

    def set_fixed_height_from_font(number_of_rows)

number_of_rows :

Number of rows of text each cell renderer is allocated, or -1

The set_fixed_height_from_font() sets the height of a renderer to explicitly be determined by the "font" and "ypad" properties set on it. This method must be called each time these properties are changed to affect the height. This function is inflexible, and should really only be used if calculating the size of a cell is too slow (i.e. a massive number of cells displayed). If number_of_rows is -1, then the fixed height is unset, and the height is determined by the properties again.

Signals

The "edited" gtk.CellRendererText Signal

    def callback(cellrenderertext, path, new_text, user_param1, ...)

`cellrenderertext` :	the cellrenderertext that received the "edited" signal
`path` :	the path string of the cellrenderertext
`new_text` :	the new text of the cellrenderertext
`user_param1` :	the first user parameter (if any) specified with the `connect`() method
`...` :	additional user parameters (if any)

The "edited" signal is emitted when the text in the cell has been edited.
