/*
* (non-Javadoc)
* For ContextMenu : MENU_OPENING replaces the SWT's MenuDetect. Since there is no such handler on a control, we needed a way
* to block the system's menu and show nothing in case there was no context menu assigned by the user. We also need to decide on
* the correct context menu before it opens.
* We do that by assigning a new and empty context menu for each control that is created.
* When the user right clicks on a control, the empty context (or a real context) shoots a MENU_OPENING.
* In this point do a few things :
* 1. If this is the 1st opening event for that click, we need to decide if that is the correct menu to be opened.
* In case its the 2nd time, the 'ContextCanOpen' flag will be true, verifying that we don't need to check the menu.
* 2. To check the menu we have separate methods for table controls and other controls.
* each type will have its own 'handleContextMenu'.
* * In table, if the clicked cell is already in edit mode, then the control we'll get here will be already a regular edit box.
* 3. In case we have discovered that the correct menu to be showed is not the one that had sent us the 'OPENING' event,
* we will cancel its opening and insteed we will set the 'ContextCanOpen' to true and call the ContextMenuStrip.Show ourselves.
* That way the correct menu will be opened.
