pub struct ColorButton(_);Expand description
The ColorButton allows to open a color chooser dialog to change
the color.
It is suitable widget for selecting a color in a preference dialog.

╰── button.color
╰── [content]ColorButton has a single CSS node with name colorbutton which
contains a button node. To differentiate it from a plain Button,
it gets the .color style class.

Implementations
Creates a new color button.
This returns a widget in the form of a small button containing a swatch representing the current selected color. When the button is clicked, a color chooser dialog will open, allowing the user to select a color. The swatch will be updated to reflect the new color when the user finishes.
Returns
a new color button
Creates a new builder-pattern struct instance to construct ColorButton objects.
This method returns an instance of ColorButtonBuilder which can be used to create ColorButton objects.
Gets the title of the color chooser dialog.
Returns
An internal string, do not free the return value
Whether the color chooser should open in editor mode.
This property should be used in cases where the palette in the editor would be redundant, such as when the color button is already part of a palette.
Whether the color chooser should open in editor mode.
This property should be used in cases where the palette in the editor would be redundant, such as when the color button is already part of a palette.
This is supported on crate feature v4_4 only.
v4_4 only.Emitted to when the color button is activated.
The ::activate signal on MenuButton is an action signal and
emitting it causes the button to pop up its dialog.
v4_4 only.Emitted when the user selects a color.
When handling this signal, use ColorChooserExt::rgba()
to find out which color was just selected.
Note that this signal is only emitted when the user changes the color. If you need to react to programmatic color changes as well, use the notify::color signal.

Tries to cast to an object of type T. This handles upcasting, downcasting
and casting between interface and interface implementors. All checks are performed at
runtime, while downcast and upcast will do many checks at compile-time already. Read more
