VB.NET, C#
This sample demonstrates how to create a Windows/Internet Explorer-like toolbar that supports resizing using WinButton controls contained in a WinPanel control.
Add WinButton button controls to a WinPanel control.
Handle the MouseHover event of a WinButton control to display a tooltip.
Handle use the DroppedDown property of a WinButton control to open or close its associated dropdown control.
Create a new instance of the WinToolBar class and set its Dock property to DockStyle.Top. When the parent form is resized, if there is not enough space to completely display a WinButton control, it will be added to the chevron button's dropdown control. If the form is resized and there is enough space made available to display a button, the last button that was added to the chevron button's dropdown control will be removed and re-added to the toolbar. If there is enough space to display all the button's the chevron button will be hidden.
