Hello,
i would like to know if it possible to get the CSS-class which is asigned to a button (for example)? I didn't find any documentation about this, just the function "getStyleContext().getProperty()", my current attempt:

Value value;
bArr[0].getStyleContext().getProperty("Class",StateFlags.NORMAL,value);


(bArr is an array of buttons).

I get the error, that 'Value' is not defined, if i use 'GValue' (as it is described here: https://developer.gnome.org/gtk3/stable/GtkStyleContext.html#gtk-style-context-get-property) i get 'function is not callable with GValue'

Any ideas? Thanks alot!

widget.getStyleContext().listClasses() to get a list of all classes assigned to the widget. If you just want to see if a specific class is assigned to the widget you can use widget.getStyleContext().hasClass()

Thanks a lot for your answer. Do you know how i can get the first classname as string from the widget? I don't understand how the return type 'GList' is organized.

ListG has a D specific method called toArray that allows you to convert it to a typed array, so you could use it in this case to get a string[] out of it.

"Type T wraps should match the type of the data"

Does string match the type of the data? What is the type of the data? How do i tell the function that i want the Array as a string array? I am not familiar with Types and what 'TC' or 'T' is, i am afraid.

toArray currently only works for GtkD classes, so it doesn't work for lists of stings.

ListG is a linked list, the data is stored in the data property. to iterate over the list do something like this:

```
ListG list = widget.getStyleContext().listClasses();

while(list !is null)
{
	string str = to!string(cast(char*)list.data);

	//do something with str.

	list = list.next;
}
```
