New Classes: TGSplitFrame, TGShapedFrame, TGEventHandler

These three classes have been primarily developed to be used in EVE. For an example of how to use them, see tutorials/eve/SplitGLView.C (this macro is used as a plugin by tutorials/eve/alice_esd_split.C).

TGSplitFrame is a horizontally or vertically splittable composite frame. Once split, each part will contain a new TGSplitFrame, separated by a TGSplitter.
TGShapedFrame is a TGCompositeFrame on which a custom shape is applied, starting from a picture file, by taking its transparency mask, and then applying the picture as background.
TGEventHandler is a Base Event Handler class allowing to delegate event handling (a base class for GL event handlers).

TGListTree

TGListTreeItem is now a base class and TGListTreeItemStd is the standard implementation (modification required by EVE).
Switched the icon and checkbox position in TGListTreeItem.
Added custom user control flags, with their getters and setters and three new signal methods (required by EVE). All these were implemented for better control of the TGListTree behavior.
- fUserControlled is a flag to take over the control
- fEventHandled is a flag to tell TGListTree that the current event has been processed by user.
- MouseOver(TGListTreeItem *entry)
- MouseOver(TGListTreeItem *entry, UInt_t mask)
- Clicked(TGListTreeItem *entry, Int_t btn, UInt_t mask, Int_t x, Int_t y)
The new DrawOutline() method draws a colored outline around a list tree item following the mouse position.
Implemented correct keyboard navigation.
Improvements for list trees containing a large number of items (i.e. one million).

TGTab

Added a new signal method Removed(Int_t id) to notify when a tab was removed.

TGListBox

Fixed flickering problem on Windows.

TGDockableFrame

Introduced the fFixedSize option, to let user choose if the undocked frame may be resized or not. Keep the (fixed) original docked frame size when undocked (i.e. for menus and toolbars).

TGShutter

Two helper methods added:
- SetSelectedItem(const char *name) - switch to the shutter section 'name'.
- EnableItem(const char *name, Bool_t on) - enable/disable the shutter section 'name' according to the value of the second parameter 'on'.

TGFileDialog

The File Open/Close dialogs show the list of all available (mounted) drives on Windows.

Hierarchical context menus.

Modal Dialogs

On Windows, any modal dialog now stays on top of its parent (true modal mode).

Context Menus

The context menu of ROOT classes can be created with hierarchical sub-menus, which are more convenient and offer better organization. This makes possible to access more class methods from the context menu (without having the menu becoming larger than the screen). The next is an example of the hierarchihal submenu structure shown below.

 void SetLevelOne(EPaletteType  palette = pal3); // *MENU={Hierarchy="Candidates/SetLevelOne"}*
 void SetPalette(EPaletteType palette = pal3);   // *SUBMENU={Hierarchy="Candidates/SetPalette"}*
 void SetCatalog(const char * = "HESS") { }      // *MENU={Hierarchy="Candidates/SetCatalog"}*
 void AddCatalog(const char * = "HESS") { }      // *MENU={Hierarchy="Candidates/AddCatalog"}*
 void RemoveCatalog(const char *  = "HESS") { }  // *MENU={Hierarchy="Candidates/RemoveCatalog"}*
 void AddCandidate(const char * = "NAME") { }    // *MENU={Hierarchy="Candidates/AddCandidate"}*

 EPaletteType fPalette; //*OPTION={GetMethod="GetPalette";SetMethod="SetPalette";Items=(PrettyPalette="PrettyPalette",SchlenkPalette="Schlenk",pal3="Pal3",pal4="Pal4")}*

Hierarchical context menus.

GUI HTML

Implemented controls handling (text buttons, radio buttons and check buttons)
Implemented signals for these controls:
- ButtonClicked(const char *name, const char *val)
- SubmitClicked(const char *val)
- CheckToggled(const char *name, Bool_t on, const char *val)
- RadioChanged(const char *name, const char *val)

GUI Builder

Robustness has been improved and several bugs fixed.
