/*
|
||||
* GlassPanelForm - A transparent form that is placed over an ObjectListView
|
||||
* to allow flicker-free overlay images during scrolling.
|
||||
*
|
||||
* Author: Phillip Piper
|
||||
* Date: 14/04/2009 4:36 PM
|
||||
*
|
||||
* Change log:
|
||||
* 2010-08-18 JPP - Added WS_EX_TOOLWINDOW style so that the form won't appear in Alt-Tab list.
|
||||
* v2.4
|
||||
* 2010-03-11 JPP - Work correctly in MDI applications -- more or less. Actually, less than more.
|
||||
* They don't crash but they don't correctly handle overlapping MDI children.
|
||||
* Overlays from one control are shown on top of other other windows.
|
||||
* 2010-03-09 JPP - Correctly Unbind() when the related ObjectListView is disposed.
|
||||
* 2009-10-28 JPP - Use FindForm() rather than TopMostControl, since the latter doesn't work
|
||||
* as I expected when the OLV is part of an MDI child window. Thanks to
|
||||
* wvd_vegt who tracked this down.
|
||||
* v2.3
|
||||
* 2009-08-19 JPP - Only hide the glass pane on resize, not on move
|
||||
* - Each glass panel now only draws one overlays
|
||||
* v2.2
|
||||
* 2009-06-05 JPP - Handle when owning window is a topmost window
|
||||
* 2009-04-14 JPP - Initial version

||||

|

* ToolTipControl - A limited wrapper around a Windows tooltip control
|
||||
*
|
||||
* For some reason, the ToolTip class in the .NET framework is implemented in a significantly
|
||||
* different manner to other controls. For our purposes, the worst of these problems
|
||||
* is that we cannot get the Handle, so we cannot send Windows level messages to the control.

||||

|
||||
* Change log:
|
||||
* v2.3
|

* 2009-06-13 JPP - Moved ToolTipShowingEventArgs to Events.cs
|

* v2.2
|
||||
* 2009-06-06 JPP - Fixed some Vista specific problems
