Class
GtkSnapshot
Description [src]
final class Gtk.Snapshot : Gdk.Snapshot
{
/* No available fields */
}Assists in creating GskRenderNodes for widgets.
It functions in a similar way to a cairo context, and maintains a stack of render nodes and their associated transformations.
The node at the top of the stack is the one that gtk_snapshot_append_…()
functions operate on. Use the gtk_snapshot_push_…() functions and
gtk_snapshot_pop() to change the current node.
The typical way to obtain a GtkSnapshot object is as an argument to
the Gtk.WidgetClass.snapshot vfunc. If you need to create your own
GtkSnapshot, use gtk_snapshot_new().
Instance methods
gtk_snapshot_append_cairo
Creates a new GskCairoNode and appends it to the current
render node of snapshot, without changing the current node.
gtk_snapshot_append_color
Creates a new render node drawing the color into the
given bounds and appends it to the current render node
of snapshot.
gtk_snapshot_append_layout
Creates render nodes for rendering layout in the given foregound color
and appends them to the current node of snapshot without changing the
current node. The current theme’s foreground color for a widget can be
obtained with gtk_widget_get_color().
gtk_snapshot_append_linear_gradient
Appends a linear gradient node with the given stops to snapshot.
gtk_snapshot_append_node
Appends node to the current render node of snapshot,
without changing the current node.
gtk_snapshot_append_radial_gradient
Appends a radial gradient node with the given stops to snapshot.
gtk_snapshot_append_repeating_linear_gradient
Appends a repeating linear gradient node with the given stops to snapshot.
gtk_snapshot_append_repeating_radial_gradient
Appends a repeating radial gradient node with the given stops to snapshot.
gtk_snapshot_append_scaled_texture
Creates a new render node drawing the texture
into the given bounds and appends it to the
current render node of snapshot.
since: 4.10
gtk_snapshot_append_texture
Creates a new render node drawing the texture
into the given bounds and appends it to the
current render node of snapshot.
gtk_snapshot_free_to_paintable
Returns a paintable for the node that was
constructed by snapshot and frees snapshot.
gtk_snapshot_gl_shader_pop_texture
Removes the top element from the stack of render nodes and
adds it to the nearest GskGLShaderNode below it.
deprecated: 4.16
gtk_snapshot_pop
Removes the top element from the stack of render nodes, and appends it to the node underneath it.
gtk_snapshot_push_color_matrix
Modifies the colors of an image by applying an affine transformation in RGB space.
gtk_snapshot_push_cross_fade
Snapshots a cross-fade operation between two images with the
given progress.
gtk_snapshot_push_fill
Fills the area given by path and fill_rule with an image and discards everything
outside of it.
since: 4.14
gtk_snapshot_push_mask
Until the first call to gtk_snapshot_pop(), the
mask image for the mask operation will be recorded.
since: 4.10
gtk_snapshot_push_stroke
Strokes the given path with the attributes given by stroke and
an image.
since: 4.14
gtk_snapshot_render_background
Creates a render node for the CSS background according to context,
and appends it to the current node of snapshot, without changing
the current node.
deprecated: 4.10
gtk_snapshot_render_focus
Creates a render node for the focus outline according to context,
and appends it to the current node of snapshot, without changing
the current node.
deprecated: 4.10
gtk_snapshot_render_frame
Creates a render node for the CSS border according to context,
and appends it to the current node of snapshot, without changing
the current node.
deprecated: 4.10
gtk_snapshot_render_insertion_cursor
Draws a text caret using snapshot at the specified index of layout.
deprecated: 4.10
gtk_snapshot_render_layout
Creates a render node for rendering layout according to the style
information in context, and appends it to the current node of snapshot,
without changing the current node.
deprecated: 4.10
gtk_snapshot_restore
Restores snapshot to the state saved by a preceding call to
gtk_snapshot_save() and removes that state from the stack of
saved states.
gtk_snapshot_rotate
Rotates @snapshot‘s coordinate system by angle degrees in 2D space -
or in 3D speak, rotates around the Z axis. The rotation happens around
the origin point of (0, 0) in the snapshot‘s current coordinate system.
gtk_snapshot_to_paintable
Returns a paintable encapsulating the render node
that was constructed by snapshot.
Signals
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
