Example 1
This example inserts a combo box as the first item in a panel and binds it with the "Ue_ComboBoxSelectionChanged" user event, and then inserts another combo box as the first item in a group and binds it with the same "Ue_ComboBoxSelectionChanged" user event.
Long ll_Handle_Category, ll_Handle_Panel, ll_Handle_ComboBox, ll_Handle_Group
ll_Handle_Category = rbb_1.InsertCategoryFirst ("MyCategory")
ll_Handle_Panel = rbb_1.InsertPanelFirst (ll_Handle_Category, "MyPanel", "AddSmall!")
ll_Handle_ComboBox = rbb_1.InsertComboBoxFirst (ll_Handle_Panel, "Ue_ComboBoxSelectionChanged")
//Group
ll_Handle_Group = rbb_1.InsertGroupLast (ll_Handle_Panel)
ll_Handle_ComboBox = rbb_1.InsertComboBoxFirst (ll_Handle_Group, "Ue_ComboBoxSelectionChanged")
Example 2
This example inserts the "MyComboBox" combo box as the first item in a panel and binds it with the "Ue_ComboBoxSelectionChanged", "Ue_ComboBoxSelected", and "Ue_ComboBoxModified" user events. It first defines a combo box item with various properties (including Label, PictureName, SelectionChanged, Selected, Modified etc.) and then inserts it as the first item in a panel.
Long ll_Handle_Category, ll_Handle_Panel, ll_Handle_ComboBox
RibbonComboBoxItem lr_ComboBox
ll_Handle_Category = rbb_1.InsertCategoryFirst ("MyCategory")
ll_Handle_Panel = rbb_1.InsertPanelFirst (ll_Handle_Category, "MyPanel", "AddSmall!")
lr_ComboBox.Label = "MyComboBox"
lr_ComboBox.PictureName = "HelpSmall!"
lr_ComboBox.SelectionChanged = "Ue_ComboBoxSelectionChanged"
lr_ComboBox.Selected = "Ue_ComboBoxSelected"
lr_ComboBox.Modified = "Ue_ComboBoxModified"
ll_Handle_ComboBox = rbb_1.InsertComboBoxFirst (ll_Handle_Panel, lr_ComboBox)
