How to populate a Combo Box in GTK3 using Glade

This post will show how to use Glade to list combo box items with GTK3 since I could not find any other tutorials and it took me a while to figure it out.  No coding necessary!

Step 1:  Insert the combo box. A GtkComboBox will be created.

Step 2: Select the combo box.  In the General Properties click the ... button next to ComboBox Model and click new.  A new GtkListStore will be created and set to the combo box's model.

Step 3: With the combo box selected, open the Combo Editor by clicking the edit button from the toolbar.

Step 4; Add some columns to the combo box's liststore.  Use type: gchararry for text.  Insert any other model columns at this time as well.

Step 5: Insert data into the liststore by scrolling down in the Combo Editor and clicking the + to add a new row.  Enter the data needed for each row.

Step 6: Click the Hierarchy tab and then click add.  A new GtkCellRendererText will be created.

Step 7: Under properties and attributes, change the Text: from unset to the gchararray column of the liststore that you wish to have displayed.

Step 8 (optional):  If you want an item selected by default, click back on the General tab and set the Active item to the row index of the liststore containing the default value.

Step 9: Close the Combo Editor and there you have a populated Combo Box!
