TGFrame, TGCompositeFrame, TGVerticalFrame, TGHorizontalFrame,
TGMainFrame, TGTransientFrame and TGGroupFrame
The frame classes describe the different "dressed" GUI windows.
The TGFrame class is a subclasses of TGWindow, and is used as base
class for some simple widgets (buttons, labels, etc.).
It provides:
- position & dimension fields
- an 'options' attribute (see constant above)
- a generic event handler
- a generic layout mechanism
- a generic border
The TGCompositeFrame class is the base class for composite widgets
(menu bars, list boxes, etc.).
It provides:
- a layout manager
- a frame container (TList *)
The TGVerticalFrame and TGHorizontalFrame are composite frame that
layout their children in vertical or horizontal way.
The TGMainFrame class defines top level windows that interact with
the system Window Manager.
The TGTransientFrame class defines transient windows that typically
are used for dialogs windows.
The TGGroupFrame is a composite frame with a border and a title.
It is typically used to group a number of logically related widgets
visually together.
/*
*/
TGFrame(const TGWindow *p, UInt_t w, UInt_t h,
UInt_t options, ULong_t back)
: TGWindow(p, 0, 0, w, h, 0, 0, 0, 0, 0, options)
Create a TGFrame object. Options is an OR of the EFrameTypes.
TGFrame(TGClient *c, Window_t id, const TGWindow *parent)
: TGWindow(c, id, parent)
Create a frame using an externally created window. For example
to register the root window (called by TGClient), or a window
created via TVirtualX::InitWindow() (id is obtained with
TVirtualX::GetWindowID()).
void DeleteWindow()
Delete window. Use single shot timer to call final delete method.
We use this inderect way since deleting the window in its own
execution "thread" can cause side effects because frame methods
can still be called while the window object has already been deleted.
void ChangeBackground(ULong_t back)
Change frame background color.
void SetBackgroundColor(Pixel_t back)
Set background color (override from TGWindow base class).
Same effect as ChangeBackground().
void ChangeOptions(UInt_t options)
Change frame options. Options is an OR of the EFrameTypes.
void AddInput(UInt_t emask)
Add events specified in the emask to the events the frame should handle.
void RemoveInput(UInt_t emask)
Remove events specified in emask from the events the frame should handle.
void Draw3dRectangle(UInt_t type, Int_t x, Int_t y,
UInt_t w, UInt_t h)
void DrawBorder()
Draw frame border.
void DoRedraw()
Redraw the frame.
Bool_t HandleConfigureNotify(Event_t *event)
This event is generated when the frame is resized.
Bool_t HandleEvent(Event_t *event)
Handle all frame events. Events are dispatched to the specific
event handlers.
void Move(Int_t x, Int_t y)
Move frame.
void Resize(UInt_t w, UInt_t h)
Resize the frame.
If w=0 && h=0 - Resize to deafult size
void Resize(TGDimension size)
Resize the frame.
void MoveResize(Int_t x, Int_t y, UInt_t w, UInt_t h)
Move and/or resize the frame.
If w=0 && h=0 - Resize to deafult size
void SendMessage(const TGWindow *w, Long_t msg, Long_t parm1, Long_t parm2)
Send message (i.e. event) to window w. Message is encoded in one long
as message type and up to two long parameters.
Bool_t HandleClientMessage(Event_t *event)
Handle a client message. Client messages are the ones sent via
TGFrame::SendMessage (typically by widgets).
ULong_t GetDefaultFrameBackground()
Get default frame background.
ULong_t GetDefaultSelectedBackground()
Get default selected frame background.
ULong_t GetWhitePixel()
Get white pixel value.
ULong_t GetBlackPixel()
Get black pixel value.
const TGGC& GetBlackGC()
Get black graphics context.
const TGGC& GetWhiteGC()
Get white graphics context.
const TGGC& GetHilightGC()
Get highlight color graphics context.
const TGGC& GetShadowGC()
Get shadow color graphics context.
const TGGC& GetBckgndGC()
Get background color graphics context.
Time_t GetLastClick()
Get time of last mouse click.
void Print(Option_t *option) const
Print window id.
void SaveUserColor(ofstream &out, Option_t *)
Save a user color in a C++ macro file - used in SavePrimitive().
TString GetOptionString() const
Returns a frame option string - used in SavePrimitive().
void SavePrimitive(ofstream &out, Option_t *option)
Save a frame widget as a C++ statement(s) on output stream out.
