Provided Methods§
sourcefn add_class(&self, class_name: &str)
👎Deprecated: Since 4.10
fn add_class(&self, class_name: &str)
Adds a style class to @self, so later uses of the style context will make use of this new class for styling.
In the CSS file format, a Entry defining a “search”
class, would be matched by:
entry.search { ... }
While any widget defining a “search” class would be matched by:
.search { ... }
§Deprecated since 4.10
Use WidgetExt::add_css_class() instead
§class_name
class name to use in styling
sourcefn add_provider(&self, provider: &impl IsA<StyleProvider>, priority: u32)
👎Deprecated: Since 4.10
fn add_provider(&self, provider: &impl IsA<StyleProvider>, priority: u32)
Adds a style provider to @self, to be used in style construction.
Note that a style provider added by this function only affects
the style of the widget to which @self belongs. If you want
to affect the style of all widgets, use
StyleContext::add_provider_for_display().
Note: If both priorities are the same, a StyleProvider
added through this function takes precedence over another added
through StyleContext::add_provider_for_display().
§Deprecated since 4.10
Use style classes instead
§provider
§priority
the priority of the style provider. The lower
it is, the earlier it will be used in the style construction.
Typically this will be in the range between
GTK_STYLE_PROVIDER_PRIORITY_FALLBACK and
GTK_STYLE_PROVIDER_PRIORITY_USER
sourcefn color(&self) -> RGBA
👎Deprecated: Since 4.10
fn color(&self) -> RGBA
Gets the foreground color for a given state.
§Deprecated since 4.10
Use WidgetExt::color() instead
§Returns
§color
return value for the foreground color
sourcefn display(&self) -> Display
👎Deprecated: Since 4.10
fn display(&self) -> Display
Returns the gdk::Display to which @self is attached.
§Deprecated since 4.10
Use WidgetExt::display() instead
§Returns
a gdk::Display.
sourcefn scale(&self) -> i32
👎Deprecated: Since 4.10
fn scale(&self) -> i32
Returns the scale used for assets.
§Deprecated since 4.10
Use WidgetExt::scale_factor() instead
§Returns
the scale
sourcefn state(&self) -> StateFlags
👎Deprecated: Since 4.10
fn state(&self) -> StateFlags
Returns the state used for style matching.
This method should only be used to retrieve the StateFlags
to pass to StyleContext methods, like
padding().
If you need to retrieve the current state of a Widget, use
WidgetExt::state_flags().
§Deprecated since 4.10
Use WidgetExt::state_flags() instead
§Returns
the state flags
sourcefn lookup_color(&self, color_name: &str) -> Option<RGBA>
👎Deprecated: Since 4.10
fn lookup_color(&self, color_name: &str) -> Option<RGBA>
sourcefn remove_class(&self, class_name: &str)
👎Deprecated: Since 4.10
fn remove_class(&self, class_name: &str)
Removes @class_name from @self.
§Deprecated since 4.10
Use WidgetExt::remove_css_class() instead
§class_name
class name to remove
sourcefn remove_provider(&self, provider: &impl IsA<StyleProvider>)
👎Deprecated: Since 4.10
fn remove_provider(&self, provider: &impl IsA<StyleProvider>)
sourcefn save(&self)
👎Deprecated: Since 4.10
fn save(&self)
Saves the @self state.
This allows temporary modifications done through
add_class(),
remove_class(),
set_state() to be quickly
reverted in one go through restore().
The matching call to restore()
must be done before GTK returns to the main loop.
§Deprecated since 4.10
This API will be removed in GTK 5
sourcefn set_display(&self, display: &impl IsA<Display>)
👎Deprecated: Since 4.10
fn set_display(&self, display: &impl IsA<Display>)
Attaches @self to the given display.
The display is used to add style information from “global”
style providers, such as the display’s Settings instance.
If you are using a StyleContext returned from
WidgetExt::style_context(), you do not need to
call this yourself.
§Deprecated since 4.10
You should not use this api
§display
sourcefn set_state(&self, flags: StateFlags)
👎Deprecated: Since 4.10
fn set_state(&self, flags: StateFlags)
sourcefn to_string(&self, flags: StyleContextPrintFlags) -> GString
👎Deprecated: Since 4.10
fn to_string(&self, flags: StyleContextPrintFlags) -> GString
Converts the style context into a string representation.
The string representation always includes information about the name, state, id, visibility and style classes of the CSS node that is backing @self. Depending on the flags, more information may be included.
This function is intended for testing and debugging of the CSS implementation in GTK. There are no guarantees about the format of the returned string, it may change.
§Deprecated since 4.10
This api will be removed in GTK 5
§flags
Flags that determine what to print
§Returns
a newly allocated string representing @self
