TGView
A TGView provides the infrastructure for text viewer and editor
widgets. It provides a canvas (TGViewFrame) and (optionally) a
vertical and horizontal scrollbar and methods for marking and
scrolling.
The TGView (and derivatives) will generate the following
event messages:
kC_TEXTVIEW, kTXT_ISMARKED, widget id, [true|false]
kC_TEXTVIEW, kTXT_DATACHANGE, widget id, 0
kC_TEXTVIEW, kTXT_CLICK2, widget id, position (y << 16) | x)
kC_TEXTVIEW, kTXT_CLICK3, widget id, position (y << 16) | x)
kC_TEXTVIEW, kTXT_F3, widget id, true
kC_TEXTVIEW, kTXT_OPEN, widget id, 0
kC_TEXTVIEW, kTXT_CLOSE, widget id, 0
kC_TEXTVIEW, kTXT_SAVE, widget id, 0
TGView(const TGWindow *p, UInt_t w, UInt_t h, Int_t id,
UInt_t xMargin, UInt_t yMargin, UInt_t options,
UInt_t sboptions, ULong_t back)
: TGCompositeFrame(p, w, h, options, GetDefaultFrameBackground())
Create an editor view, containing an TGEditorFrame and (optionally)
a horizontal and vertical scrollbar.
~TGView()
Delete view.
void Clear(Option_t *)
Clear view.
void SetVisibleStart(Int_t newTop, Int_t direction)
Scroll view in specified direction to make newTop the visible location.
Bool_t HandleExpose(Event_t *event)
Handle expose events.
Bool_t HandleCrossing(Event_t *event)
Handle mouse crossing event.
Bool_t HandleTimer(TTimer *)
Handle scroll timer.
Bool_t HandleButton(Event_t *event)
Handle mouse button event in text editor.
Bool_t HandleDoubleClick(Event_t *event)
handle double click
Bool_t HandleMotion(Event_t *event)
Handle mouse motion event in the text editor widget.
Bool_t ProcessMessage(Long_t msg, Long_t parm1, Long_t)
Process scrollbar messages.
void Layout()
Layout the components of view.
void HLayout()
Horizontal layout of widgets (canvas, scrollbar).
void VLayout()
Vertical layout of widgets (canvas, scrollbar).
void SetSBRange(Int_t direction)
Set the range for the kVertical or kHorizontal scrollbar.
void SetHsbPosition(Long_t newPos)
Set position of horizontal scrollbar.
void SetVsbPosition(Long_t newPos)
Set position of vertical scrollbar.
void ShowBottom()
Show bottom of the page.
void ShowTop()
Show top of the page.
void DrawBorder()
Draw the border of the text edit widget.
void ScrollCanvas(Int_t new_top, Int_t direction)
Scroll the canvas to new_top in the kVertical or kHorizontal direction.
