Question

Where are, In the Tool Box, the controls that are shown in the example? (Arrow HeadComboBox, LineWeight ComboBox, Color ComboBox, PlotStyle ComboBox, Font ComboBox, etc.)

Answer

All the different types of ComboBoxes are set as a property style of the ComboBox. So if you want a Color ComboBox for example, draw a ComboBox, right click on it, click 'Properties' then select one of the styles shown in the property wizard dialog box. This will change the ComboBox to a Color ComboBox.
