如何使Gtk.Frame的标签变粗？

Question

Usually, for Labels you can do something like this:

Label label = new Label ("<b>Some Text</b>") {
    UseMarkup = true
};

However, Gtk.Frame's label is just a string, not a full-fledged Label. I can't find an option to use markup. How to I enable markup, or otherwise set the label to be bold?

Answer 1

GtkFrame的标签可以是任何小部件 ，如果您愿意，您可以使用自己的GtkLabel。

Answer 2

Gtk.Frame has the possibility of setting any widget as "label". You can access this widget by accessing the property LabelWidget . Using this possibility, you can set a new Gtk.Label with any properties you need.

var frmExample = new Gtk.Frame();
frmExample.LabelWidget = new Gtk.Label() { Markup = "<b>Example</b>" };
this.Add( frmExample );
this.showAll();

The solution is actually simpler for the specific case of a label with markup. I've found that the Gtk.Frame already has a Gtk.Label attached, and, as you said, you can set the markup property to true .

var frmExample = new Gtk.Frame( "<b>Example</b>" );
( (Gtk.Label) this.frmExample.LabelWidget ).UseMarkup = true;
this.Add( frmExample );
this.showAll();

Hope this helps.

Not sure how it would look in C# but in plain C you could do this:

  frame = GTK_WIDGET (g_object_new (GTK_TYPE_FRAME, "label", "", NULL)); label = gtk_label_new(_("<b>Scope</b>")); gtk_label_set_use_markup(GTK_LABEL(label), TRUE); gtk_frame_set_label_widget (GTK_FRAME(frame), label);
