Description

GtkStyleContext is an object that stores styling information affecting a widget.

In order to construct the final style information, GtkStyleContext queries information from all attached GtkStyleProviders. Style providers can be either attached explicitly to the context through gtk_style_context_add_provider(), or to the display through gtk_style_context_add_provider_for_display(). The resulting style is a combination of all providers’ information in priority order.

For GTK+ widgets, any GtkStyleContext returned by gtk_widget_get_style_context() will already have a GdkDisplay and RTL/LTR information set. The style context will also be updated automatically if any of these settings change on the widget.

Style Classes

Widgets can add style classes to their context, which can be used to associate different styles by class. The documentation for individual widgets lists which style classes it uses itself, and which style classes may be added by applications to affect their appearance.

GTK+ defines macros for a number of style classes.


Custom styling in UI libraries and applications

If you are developing a library with custom GtkWidgets that render differently than standard components, you may need to add a GtkStyleProvider yourself with the GTK_STYLE_PROVIDER_PRIORITY_FALLBACK priority, either a GtkCssProvider or a custom object implementing the GtkStyleProvider interface. This way themes may still attempt to style your UI elements in a different way if needed so.

If you are using custom styling on an applications, you probably want then to make your style information prevail to the theme’s, so you must use a GtkStyleProvider with the GTK_STYLE_PROVIDER_PRIORITY_APPLICATION priority, keep in mind that the user settings in XDG_CONFIG_HOME/gtk-4.0/gtk.css will still take precedence over your changes, as it uses the GTK_STYLE_PROVIDER_PRIORITY_USER priority.

Functions

gtk_style_context_add_provider ()

void
gtk_style_context_add_provider (GtkStyleContext *context,
                                GtkStyleProvider *provider,
                                guint priority);

Adds a style provider to context , to be used in style construction. Note that a style provider added by this function only affects the style of the widget to which context belongs. If you want to affect the style of all widgets, use gtk_style_context_add_provider_for_display().

Note: If both priorities are the same, a GtkStyleProvider added through this function takes precedence over another added through gtk_style_context_add_provider_for_display().

Parameters

context

a GtkStyleContext

 

provider

a GtkStyleProvider

 

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

 

gtk_style_context_add_provider_for_display ()

void
gtk_style_context_add_provider_for_display
                               (GdkDisplay *display,
                                GtkStyleProvider *provider,
                                guint priority);

Adds a global style provider to display , which will be used in style construction for all GtkStyleContexts under display .

GTK+ uses this to make styling information from GtkSettings available.

Note: If both priorities are the same, A GtkStyleProvider added through gtk_style_context_add_provider() takes precedence over another added through this function.

Parameters

display

a GdkDisplay

 

provider

a GtkStyleProvider

 

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

In the CSS file format, a GtkEntry defining a “search” class, would be matched by:

1
entry.search { ... }

While any widget defining a “search” class would be matched by:

1
.search { ... }

Parameters

a GtkStyleContext

 

class_name

class name to use in styling
