Weifenluo. winformsui. Docking -- a little improvement on dockpanel

From: http://www.cnblogs.com/yvesliao/archive/2008/08/26/1276609.html

1. When you double-click a tab, the current tab is directly separated from the frame of the main form to form a floating form. This is not what I want. I changed it to double-click to close it.
In the wndproc method of dockpanestripbase. CS, the left-click message is re-processed (the comment below is the original method, and the line below is changed ):

[Securitypermission (securityaction. linkdemand, flags = securitypermissionflag. unmanagedcode)]
Protected override void wndproc (ref message m)
{
If (M. MSG = (INT) win32.msgs. wm_lbuttondblclk)
{
Base. wndproc (ref m );

Int Index = hittest ();
If (dockpane. dockpanel. allowenduserdocking & Index! =-1)
{
Idockcontent content = tabs [Index]. content;
// If (content. dockhandler. checkdockstate (! Content. dockhandler. isfloat )! = Dockstate. Unknown)
// Content. dockhandler. isfloat =! Content. dockhandler. isfloat; // indicates that the window is restored to the initial size and is detached from any dock.
If (content. dockhandler. hideonclose)
Content. dockhandler. Hide (); // hide
Else
Content. dockhandler. Close (); // close

}

 

Return;
}

Base. wndproc (ref m );
Return;
}

2. Many forms have a right-click menu in the tab, and the right-click menu is closed, so it is best to inherit dockcontent so that other forms have this right-click menu as long as they inherit it.
