Struct gtk4::builders::GLAreaBuilder

pub struct GLAreaBuilder { /* private fields */ }

A builder-pattern type to construct GLArea objects.

Implementations

impl GLAreaBuilder

pub fn new() -> Self

Create a new GLAreaBuilder.

pub fn build(self) -> GLArea

Build the GLArea.

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 seldom, but takes a long time to redraw.

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.

Setting this property will enable GL’s depth testing as a side effect. If you don’t need depth testing, you should call glDisable(GL_DEPTH_TEST) in your GtkGLArea::render handler.

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 can_focus(self, can_focus: bool) -> Self

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.

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

Whether the widget can receive pointer events.

pub fn css_classes(self, css_classes: Vec<String>) -> Self

A list of css classes applied to this widget.

pub fn css_name(self, css_name: &str) -> Self

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.

pub fn cursor(self, cursor: &Cursor) -> Self

The cursor used by @widget.

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.

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

Whether this widget itself will accept the input focus.

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

How to distribute horizontal space if widget gets extra space.

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

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 signal::Widget::query-tooltip to determine whether it will provide a tooltip or not.

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

Override for height request of the widget.

If this is -1, the natural request will be used.

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

Whether to expand horizontally.

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

Whether to use the hexpand property.

pub fn layout_manager(self, layout_manager: &impl IsA<LayoutManager>) -> Self

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.

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: &str) -> Self

The name of the widget.

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

The requested opacity of the widget.

pub fn overflow(self, overflow: Overflow) -> Self

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.

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

Whether the widget will receive the default action when it is focused.

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

Whether the widget responds to input.

pub fn tooltip_markup(self, tooltip_markup: &str) -> Self

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: property::Widget::has-tooltip will automatically be set to true and there will be taken care of signal::Widget::query-tooltip in the default signal handler.

Note that if both property::Widget::tooltip-text and property::Widget::tooltip-markup are set, the last one wins.

pub fn tooltip_text(self, tooltip_text: &str) -> 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: property::Widget::has-tooltip will automatically be set to true and there will be taken care of signal::Widget::query-tooltip in the default signal handler.

Note that if both property::Widget::tooltip-text and property::Widget::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.

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

Whether to expand vertically.

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

Whether to use the vexpand property.

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

Whether the widget is visible.

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

Override for width request of the widget.

If this is -1, the natural request will be used.

pub fn accessible_role(self, accessible_role: AccessibleRole) -> Self

The accessible role of the given Accessible implementation.

The accessible role cannot be changed once set.
