Implementations

source

impl IconInfo

source

pub fn for_pixbuf(icon_theme: &impl IsA<IconTheme>, pixbuf: &Pixbuf) -> IconInfo

Creates a IconInfo for a gdk_pixbuf::Pixbuf.

pub fn base_scale(&self) -> i32

Gets the base scale for the icon. The base scale is a scale for the icon that was specified by the icon theme creator. For instance an icon drawn for a high-dpi screen with window scale 2 for a base size of 32 will be 64 pixels tall and have a base scale of 2.

Returns

the base scale

source

pub fn base_size(&self) -> i32

Gets the base size for the icon. The base size is a size for the icon that was specified by the icon theme creator. This may be different than the actual size of image; an example of this is small emblem icons that can be attached to a larger icon. These icons will be given the same base size as the larger icons to which they are attached.

Note that for scaled icons the base size does not include the base scale.

Returns

the base size, or 0, if no base size is known for the icon.

source

pub fn filename(&self) -> Option<PathBuf>

Gets the filename for the icon. If the IconLookupFlags::USE_BUILTIN flag was passed to IconThemeExt::lookup_icon(), there may be no filename if a builtin icon is returned; in this case, you should use gtk_icon_info_get_builtin_pixbuf().

Returns

the filename for the icon, or None if gtk_icon_info_get_builtin_pixbuf() should be used instead. The return value is owned by GTK+ and should not be modified or freed.

source

pub fn is_symbolic(&self) -> bool

Checks if the icon is symbolic or not. This currently uses only the file name and not the file contents for determining this. This behaviour may change in the future.

Returns

true if the icon is symbolic, false otherwise

source

pub fn load_icon(&self) -> Result<Pixbuf, Error>

Renders an icon previously looked up in an icon theme using IconThemeExt::lookup_icon(); the size will be based on the size passed to IconThemeExt::lookup_icon(). Note that the resulting pixbuf may not be exactly this size; an icon theme may have icons that differ slightly from their nominal sizes, and in addition GTK+ will avoid scaling icons that it considers sufficiently close to the requested size or for which the source image would have to be scaled up too far. (This maintains sharpness.). This behaviour can be changed by passing the IconLookupFlags::FORCE_SIZE flag when obtaining the IconInfo. If this flag has been specified, the pixbuf returned by this function will be scaled to the exact size.

Returns

the rendered icon; this may be a newly created icon or a new reference to an internal icon, so you must not modify the icon. Use g_object_unref() to release your reference to the icon.

source

pub fn load_icon_async<P: FnOnce(Result<Pixbuf, Error>) + 'static>(
 &self,
 cancellable: Option<&impl IsA<Cancellable>>,
 callback: P
)

Asynchronously load, render and scale an icon previously looked up from the icon theme using IconThemeExt::lookup_icon().

For more details, see load_icon() which is the synchronous version of this call.

`cancellable`

optional gio::Cancellable object, None to ignore

`callback`

a GAsyncReadyCallback to call when the request is satisfied

source

pub fn load_icon_future(
&self
) -> Pin<Box_<dyn Future<Output = Result<Pixbuf, Error>> + 'static>>

source

pub fn load_surface(
&self,
for_window: Option<&Window>
) -> Result<Surface, Error>

Renders an icon previously looked up in an icon theme using IconThemeExt::lookup_icon(); the size will be based on the size passed to IconThemeExt::lookup_icon(). Note that the resulting surface may not be exactly this size; an icon theme may have icons that differ slightly from their nominal sizes, and in addition GTK+ will avoid scaling icons that it considers sufficiently close to the requested size or for which the source image would have to be scaled up too far. (This maintains sharpness.). This behaviour can be changed by passing the IconLookupFlags::FORCE_SIZE flag when obtaining the IconInfo. If this flag has been specified, the pixbuf returned by this function will be scaled to the exact size.

`for_window`

gdk::Window to optimize drawing for, or None

Returns

the rendered icon; this may be a newly created icon or a new reference to an internal icon, so you must not modify the icon. Use cairo_surface_destroy() to release your reference to the icon.

source

pub fn load_symbolic(
 &self,
 fg: &RGBA,
 success_color: Option<&RGBA>,
 warning_color: Option<&RGBA>,
 error_color: Option<&RGBA>
) -> Result<(Pixbuf, bool ), Error>

Loads an icon, modifying it to match the system colours for the foreground, success, warning and error colors provided. If the icon is not a symbolic one, the function will return the result from load_icon().

This allows loading symbolic icons that will match the system theme.

Unless you are implementing a widget, you will want to use g_themed_icon_new_with_default_fallbacks() to load the icon.

As implementation details, the icon loaded needs to be of SVG type, contain the “symbolic” term as the last component of the icon name, and use the “fg”, “success”, “warning” and “error” CSS styles in the SVG file itself.

See the Symbolic Icons Specification for more information about symbolic icons.

`fg`

a gdk::RGBA representing the foreground color of the icon

`success_color`

a gdk::RGBA representing the warning color of the icon or None to use the default color

`warning_color`

a gdk::RGBA representing the warning color of the icon or None to use the default color

`error_color`

a gdk::RGBA representing the error color of the icon or None to use the default color (allow-none)

Returns

a gdk_pixbuf::Pixbuf representing the loaded icon

`was_symbolic`

a gboolean, returns whether the loaded icon was a symbolic one and whether the fg color was applied to it.

source

pub fn load_symbolic_async<P: FnOnce(Result<(Pixbuf, bool ), Error>) + 'static>(
 &self,
 fg: &RGBA,
 success_color: Option<&RGBA>,
 warning_color: Option<&RGBA>,
 error_color: Option<&RGBA>,
 cancellable: Option<&impl IsA<Cancellable>>,
 callback: P
)

Asynchronously load, render and scale a symbolic icon previously looked up from the icon theme using IconThemeExt::lookup_icon().

For more details, see load_symbolic() which is the synchronous version of this call.

`fg`

`success_color`

a gdk::RGBA representing the warning color of the icon or None to use the default color

`error_color`

a gdk::RGBA representing the error color of the icon or None to use the default color (allow-none)

`cancellable`

source

pub fn load_symbolic_for_context(
&self,
context: &impl IsA<StyleContext>
) -> Result<(Pixbuf, bool ), Error>

Loads an icon, modifying it to match the system colors for the foreground, success, warning and error colors provided. If the icon is not a symbolic one, the function will return the result from load_icon(). This function uses the regular foreground color and the symbolic colors with the names “success_color”, “warning_color” and “error_color” from the context.

This allows loading symbolic icons that will match the system theme.

See load_symbolic() for more details.

`context`

a StyleContext

Returns

a gdk_pixbuf::Pixbuf representing the loaded icon

`was_symbolic`

a gboolean, returns whether the loaded icon was a symbolic one and whether the fg color was applied to it.

source

 &self,
 context: &impl IsA<StyleContext>,

)
