// If you try to make any improvements here, please make sure not only that the button is visible |
|
// when the start page is opened, but also: |
|
// 1. When the user switches to another tab and back to the start page |
|
// 2. When the start page is undocked by dragging the tab |
|
// 3. When the start page is docked again (this currently *doesn't* work) |
|
// 4. The button is never duplicated, for example when switching focus to a different tool window and back |
|
|
|
// I've tried many approaches such as doing this in OnFrameIsVisibleChanged, OnActiveFrameChanged, |
|
// IVsWindowFrameNotify.OnShow using IVsWindowFrame2.Advise and even DTE.Events.WindowEvents. |
|
// With all of these approaches there are cases where the button is not recreated because the event is not fired, |
|
// and in some cases it's even fired twice. The current solution is a compromise - the common case works and |
|
// undocking the start page is presumably not that common. |
