谁用过gtk_combo_box

eexpress

原型 引用:
gtk_combo_box_set_row_span_column ()

void gtk_combo_box_set_row_span_column (GtkComboBox *combo_box,
gint row_span);

Sets the column with row span information for combo_box to be row_span. The row span column contains integers which indicate how many rows an item should span.

combo_box : A GtkComboBox.
row_span : A column in the model passed during construction.

Since 2.4



调用 代码:
gtk_combo_box_set_row_span_column(GTK_COMBO_BOX(data->O_grp), 3);
gtk_combo_box_set_column_span_column(GTK_COMBO_BOX(data->O_grp), 3);



出错 引用:
Gtk-CRITICAL **: gtk_combo_box_set_row_span_column: assertion `row_span >= -1 && row_span < col' failed
Gtk-CRITICAL **: gtk_combo_box_set_column_span_column: assertion `column_span >= -1 && column_span < col' failed




就是要多列显示而已。还不知道是不是这个。
