Struct GLAreaBuilder 

pub struct GLAreaBuilder { /* private fields */ }

A builder-pattern type to construct GLArea objects.

Implementations

impl GLAreaBuilder

pub fn auto_render(self, auto_render: bool) -> Self

If set to true the render signal will be emitted every time the widget draws. This is the default and is useful if drawing the widget is faster.

If set to false the data from previous rendering is kept around and will be used for drawing the widget the next time, unless the window is resized. In order to force a rendering GLAreaExt::queue_render() must be called. This mode is useful when the scene changes seldomly, but takes a long time to redraw.

pub fn has_alpha(self, has_alpha: bool) -> Self

If set to true the buffer allocated by the widget will have an alpha channel component, and when rendering to the window the result will be composited over whatever is below the widget.

If set to false there will be no alpha channel, and the buffer will fully replace anything below the widget.

pub fn has_depth_buffer(self, has_depth_buffer: bool) -> Self

If set to true the widget will allocate and enable a depth buffer for the target framebuffer.

pub fn has_stencil_buffer(self, has_stencil_buffer: bool) -> Self

If set to true the widget will allocate and enable a stencil buffer for the target framebuffer.

pub fn use_es(self, use_es: bool) -> Self

If set to true the widget will try to create a gdk::GLContext using OpenGL ES instead of OpenGL.

pub fn app_paintable(self, app_paintable: bool) -> Self

pub fn can_default(self, can_default: bool) -> Self

pub fn can_focus(self, can_focus: bool) -> Self

pub fn events(self, events: EventMask) -> Self

pub fn expand(self, expand: bool) -> Self

Whether to expand in both directions. Setting this sets both hexpand and vexpand

pub fn focus_on_click(self, focus_on_click: bool) -> Self

Whether the widget should grab focus when it is clicked with the mouse.

This property is only relevant for widgets that can take focus.

Before 3.20, several widgets (GtkButton, GtkFileChooserButton, GtkComboBox) implemented this property individually.

pub fn halign(self, halign: Align) -> Self

How to distribute horizontal space if widget gets extra space, see Align

pub fn has_default(self, has_default: bool) -> Self

pub fn has_focus(self, has_focus: bool) -> Self

pub fn has_tooltip(self, has_tooltip: bool) -> Self

Enables or disables the emission of query-tooltip 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.

Note that setting this property to true for the first time will change the event masks of the GdkWindows of this widget to include leave-notify and motion-notify events. This cannot and will not be undone when the property is set to false again.

pub fn height_request(self, height_request: i32) -> Self

pub fn hexpand(self, hexpand: bool) -> Self

Whether to expand horizontally. See WidgetExt::set_hexpand().

pub fn hexpand_set(self, hexpand_set: bool) -> Self

Whether to use the hexpand property. See WidgetExt::is_hexpand_set().

pub fn is_focus(self, is_focus: bool) -> Self

pub fn margin(self, margin: i32) -> Self

Sets all four sides’ margin at once. If read, returns max margin on any side.

pub fn margin_bottom(self, margin_bottom: i32) -> Self

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.

pub fn margin_end(self, margin_end: i32) -> Self

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.

pub fn margin_start(self, margin_start: i32) -> Self

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.

pub fn margin_top(self, margin_top: i32) -> Self

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.

pub fn name(self, name: impl Into<GString>) -> Self

pub fn no_show_all(self, no_show_all: bool) -> Self

pub fn opacity(self, opacity: f64) -> Self

The requested opacity of the widget. See WidgetExt::set_opacity() for more details about window opacity.

Before 3.8 this was only available in GtkWindow

pub fn parent(self, parent: &impl IsA<Container>) -> Self

pub fn receives_default(self, receives_default: bool) -> Self

pub fn sensitive(self, sensitive: bool) -> Self

pub fn tooltip_markup(self, tooltip_markup: impl Into<GString>) -> Self

Sets the text of tooltip to be the given string, which is marked up with the [Pango text markup language][PangoMarkupFormat]. 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.

pub fn tooltip_text(self, tooltip_text: impl Into<GString>) -> Self

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: 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.

pub fn valign(self, valign: Align) -> Self

How to distribute vertical space if widget gets extra space, see Align

pub fn vexpand(self, vexpand: bool) -> Self

Whether to expand vertically. See WidgetExt::set_vexpand().

pub fn vexpand_set(self, vexpand_set: bool) -> Self

Whether to use the vexpand property. See WidgetExt::is_vexpand_set().

pub fn visible(self, visible: bool) -> Self

pub fn width_request(self, width_request: i32) -> Self

pub fn build(self) -> GLArea

Build the GLArea.
