only.Expand description
Inscription
is a widget to show text in a predefined area.
You likely want to use Label
instead as this widget is intended only
for a small subset of use cases. The main scenario envisaged is inside lists
such as ColumnView
.
While a Label
sizes itself depending on the text that is displayed,
Inscription
is given a size and inscribes the given text into that
space as well as it can.
Users of this widget should take care to plan behaviour for the common case where the text doesn’t fit exactly in the allocated space, .
Properties
attributes
A list of style attributes to apply to the text of the inscription.
Readable | Writeable
markup
Utility property that sets both the text
and
attributes
properties, mainly intended for use in
GtkBuilder ui files to ease translation support and bindings.
This function uses parse_markup()
to parse the markup into text and
attributes. The markup must be valid. If you cannot ensure that, consider using
parse_markup()
and setting the two properties yourself.
Writeable
min-chars
The number of characters that should fit into the inscription at minimum.
This influences the requested width, not the width actually given to the widget, which might turn out to be larger.
Note that this is an approximate character width, so some characters might be wider and some might be thinner, so do not expect the number of characters to exactly match.
If you set this property to 0, the inscription will not request any width at all and its width will be determined entirely by its surroundings.
Readable | Writeable
min-lines
The number of lines that should fit into the inscription at minimum.
This influences the requested height, not the height actually given to the widget, which might turn out to be larger.
Note that this is an approximate line height, so if the text uses things like fancy Unicode or attribute that influence the height, the text might not fit.
If you set this property to 0, the inscription will not request any height at all and its height will be determined entirely by its surroundings.
Readable | Writeable
nat-chars
The number of characters that should ideally fit into the inscription.
This influences the requested width, not the width actually given to the widget. The widget might turn out larger as well as smaller.
If this property is set to a value smaller than min-chars
,
that value will be used. In particular, for the default value of 0, this will always
be the case.
Readable | Writeable
nat-lines
The number of lines that should ideally fit into the inscription.
This influences the requested height, not the height actually given to the widget. The widget might turn out larger as well as smaller.
If this property is set to a value smaller than min-lines
,
that value will be used. In particular, for the default value of 0, this will always
be the case.
Readable | Writeable
text
The displayed text.
Readable | Writeable
text-overflow
The overflow method to use for the text.
Readable | Writeable
wrap-mode
Controls how the line wrapping is done.
Note that unlike Label
, the default here is pango::WrapMode::WordChar
.
Readable | Writeable
xalign
The horizontal alignment of the text inside the allocated size.
Compare this to halign
, which determines how the
inscription’s size allocation is positioned in the available space.
Readable | Writeable
yalign
The vertical alignment of the text inside the allocated size.
Compare this to valign
, which determines how the
inscription’s size allocation is positioned in the available space.
Readable | Writeable
Widget
can-focus
Whether the widget or any of its descendents can accept the input focus.
This property is meant to be set by widget implementations, typically in their instance init function.
Readable | Writeable
can-target
Whether the widget can receive pointer events.
Readable | Writeable
css-classes
A list of css classes applied to this widget.
Readable | Writeable
css-name
The name of this widget in the CSS tree.
This property is meant to be set by widget implementations, typically in their instance init function.
Readable | Writeable | Construct Only
cursor
The cursor used by @widget.
Readable | Writeable
focus-on-click
Whether the widget should grab focus when it is clicked with the mouse.
This property is only relevant for widgets that can take focus.
Readable | Writeable
focusable
Whether this widget itself will accept the input focus.
Readable | Writeable
halign
How to distribute horizontal space if widget gets extra space.
Readable | Writeable
has-default
Whether the widget is the default widget.
Readable
has-focus
Whether the widget has the input focus.
Readable
has-tooltip
Enables or disables the emission of the ::query-tooltip signal on @widget.
A value of true
indicates that @widget can have a tooltip, in this case
the widget will be queried using query-tooltip
to
determine whether it will provide a tooltip or not.
Readable | Writeable
height-request
Override for height request of the widget.
If this is -1, the natural request will be used.
Readable | Writeable
hexpand
Whether to expand horizontally.
Readable | Writeable
hexpand-set
Whether to use the hexpand
property.
Readable | Writeable
layout-manager
The LayoutManager
instance to use to compute the preferred size
of the widget, and allocate its children.
This property is meant to be set by widget implementations, typically in their instance init function.
Readable | Writeable
margin-bottom
Margin on bottom side of widget.
This property adds margin outside of the widget’s normal size
request, the margin will be added in addition to the size from
WidgetExt::set_size_request()
for example.
Readable | Writeable
margin-end
Margin on end of widget, horizontally.
This property supports left-to-right and right-to-left text directions.
This property adds margin outside of the widget’s normal size
request, the margin will be added in addition to the size from
WidgetExt::set_size_request()
for example.
Readable | Writeable
margin-start
Margin on start of widget, horizontally.
This property supports left-to-right and right-to-left text directions.
This property adds margin outside of the widget’s normal size
request, the margin will be added in addition to the size from
WidgetExt::set_size_request()
for example.
Readable | Writeable
margin-top
Margin on top side of widget.
This property adds margin outside of the widget’s normal size
request, the margin will be added in addition to the size from
WidgetExt::set_size_request()
for example.
Readable | Writeable
name
The name of the widget.
Readable | Writeable
opacity
The requested opacity of the widget.
Readable | Writeable
overflow
How content outside the widget’s content area is treated.
This property is meant to be set by widget implementations, typically in their instance init function.
Readable | Writeable
parent
The parent widget of this widget.
Readable
receives-default
Whether the widget will receive the default action when it is focused.
Readable | Writeable
root
The Root
widget of the widget tree containing this widget.
This will be None
if the widget is not contained in a root widget.
Readable
scale-factor
The scale factor of the widget.
Readable
sensitive
Whether the widget responds to input.
Readable | Writeable
tooltip-markup
Sets the text of tooltip to be the given string, which is marked up with Pango markup.
Also see Tooltip::set_markup()
.
This is a convenience property which will take care of getting the
tooltip shown if the given string is not None
:
has-tooltip
will automatically be set to true
and there will be taken care of query-tooltip
in
the default signal handler.
Note that if both tooltip-text
and
tooltip-markup
are set, the last one wins.
Readable | Writeable
tooltip-text
Sets the text of tooltip to be the given string.
Also see Tooltip::set_text()
.
This is a convenience property which will take care of getting the
tooltip shown if the given string is not None

and
tooltip-markup
are set, the last one wins.

vexpand
Whether to expand vertically.
Readable | Writeable
vexpand-set
Whether to use the vexpand
property.
