Struct gdk4_win32::Win32Display

pub struct Win32Display { /* private fields */ }

Implements

gdk::prelude::DisplayExt

Implementations

impl Win32Display

pub fn win32hcursor(&self, cursor: &Cursor) -> Win32HCursor

Returns the Win32 HCURSOR wrapper object belonging to a gdk::Cursor, potentially creating the cursor object.

Be aware that the returned cursor may not be unique to @cursor. It may for example be shared with its fallback cursor.

cursor

a gdk::Cursor

Returns

a GdkWin32HCursor

pub fn set_cursor_theme(&self, name: Option<&str>, size: i32)

Sets the cursor theme from which the images for cursor should be taken.

If the windowing system supports it, existing cursors created with gdk::Cursor::from_name() are updated to reflect the theme change. Custom cursors constructed with gdk::Cursor::from_texture() will have to be handled by the application (GTK applications can learn about cursor theme changes by listening for change notification for the corresponding GtkSetting).

name

the name of the cursor theme to use, or None to unset a previously set value

size

the cursor size to use, or 0 to keep the previous size

pub fn primary_monitor(display: &impl IsA<Display>) -> Monitor

pub fn wgl_version(display: &impl IsA<Display>) -> Option<(i32, i32)>

Retrieves the version of the WGL implementation.

display

a gdk::Display

Returns

true if WGL is available

major

return location for the WGL major version

minor

return location for the WGL minor version

impl Win32Display

pub fn egl_display(&self) -> Option<Display>

Available on crate features v4_4 and egl only.

Retrieves the EGL display connection object for the given GDK display.

Returns

the EGL display

pub fn add_filter<F>(&self, filter_func: F) -> Win32DisplayFilterHandle

where F: Fn(&Self, &mut MSG, &mut i32) -> Win32MessageFilterReturn + 'static,

Adds an event filter to @window, allowing you to intercept messages before they reach GDK. This is a low-level operation and makes it easy to break GDK and/or GTK, so you have to know what you’re doing.

function

filter callback

Trait Implementations

impl Clone for Win32Display

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Win32Display

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl HasParamSpec for Win32Display

type ParamSpec = ParamSpecObject

type SetValue = Win32Display

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, Win32Display>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Win32Display

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Win32Display

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl ParentClassIs for Win32Display

type Parent = Display

impl<OT: ObjectType> PartialEq<OT> for Win32Display

fn eq(&self, other: &OT) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<OT: ObjectType> PartialOrd<OT> for Win32Display

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for Win32Display

fn static_type() -> Type

Returns the type identifier of Self.
