TGLVContainer
TGCanvas and TGViewPort and TGContainer
A TGCanvas is a frame containing two scrollbars (a horizontal and
a vertical) and a viewport. The viewport acts as the window through
which we look at the contents of the container frame.
A TGContainer frame manages a content area. It can display and
control a hierarchy of multi-column items, and provides the ability
to add new items at any time. By default it doesn't map subwindows
which are itmes of the container. In this case subwindow must
provide DrawCopy method, see for example TGLVEntry class.
It is also possible to use option which allow to map subwindows.
This option has much slower drawing speed in case of more than 1000
items placed in container. To activate this option the fMapSubwindows
data member must be set to kTRUE (for example TTVLVContainer class)
The TGContainer class can handle the keys:
o F7, Ctnrl-F - activate search dialog
o F3, Ctnrl-G - continue search
o End - go to the last item in container
o Home - go to the first item in container
o PageUp,PageDown,arrow keys - navigate inside container
o Return/Enter - equivalent to double click of the mouse button
o Contrl-A - select/activate all items.
o Space - invert selection.
TGContainer(const TGWindow *p, UInt_t w, UInt_t h,
UInt_t options, ULong_t back) :
TGCompositeFrame(p, w, h, options, back)
Create a canvas container. This is the (large) frame that contains
all the list items. It will be shown through a TGViewPort (which is
created by the TGCanvas).
~TGContainer()
Delete canvas container.
void Layout()
layout container entries
void CurrentChanged(Int_t x,Int_t y)
Emit signal when current position changed.
void CurrentChanged(TGFrame* f)
Emit signal when current selected frame changed.
void ReturnPressed(TGFrame* f)
Signal emitted when Return/Enter key pressed
It's equivalent to "double click" of mouse button
void SpacePressed(TGFrame* f)
Signal emitted when space key pressed.
Pressing space key inverts selection.
void OnMouseOver(TGFrame* f)
Signal emitted when pointer is over entry.
void Clicked(TGFrame *entry, Int_t btn)
Emit Clicked() signal.
void Clicked(TGFrame *entry, Int_t btn, Int_t x, Int_t y)
Emit Clicked() signal.
void DoubleClicked(TGFrame *entry, Int_t btn)
Emit DoubleClicked() signal.
void DoubleClicked(TGFrame *entry, Int_t btn, Int_t x, Int_t y)
Emit DoubleClicked() signal.
void SelectAll()
Select all items in the container.
SelectAll signal emitted
void UnSelectAll()
Unselect all items in the container.
void InvertSelection()
Invert the selection, all selected items become unselected and
vice versa.
void RemoveAll()
Remove all items from the container.
void RemoveItem(TGFrame *item)
Remove item from container.
const TGFrame* GetNextSelected(void **current)
Return next selected item.
void ActivateItem(TGFrameElement* el)
Activate item.
TGPosition GetPagePosition() const
Returns page position.
TGDimension GetPageDimension() const
Returns page dimension.
void SetPagePosition(const TGPosition& pos)
Set page position.
void SetPagePosition(Int_t x, Int_t y)
Set page position.
void SetPageDimension(const TGDimension& dim)
Set page dimension.
void SetPageDimension(UInt_t w, UInt_t h)
Set page dimension.
void MapSubwindows()
Map subwindows.
void DoRedraw()
Redraw content of container in the viewport region.
void DrawRegion(Int_t x, Int_t y, UInt_t w, UInt_t h)
Draw a region of container in viewport.
void ClearViewPort()
Clear view port.
Bool_t HandleExpose(Event_t *event)
Handle expose events. Do not use double buffer.
Bool_t HandleButton(Event_t *event)
Handle mouse button event in container.
Bool_t HandleDoubleClick(Event_t *event)
Handle double click mouse event.
Bool_t HandleMotion(Event_t *event)
Handle mouse motion events.
Bool_t HandleKey(Event_t *event)
The key press event handler converts a key press to some line editor
action.
void Search()
invokes search dialog. Looks for item with the entered name
void OnAutoScroll()
Autoscroll while close to & beyond The Wall
void SearchPattern()
search for entry which name begins with pattern
void RepeatSearch()
repeats search
TGFrameElement* FindFrame(Int_t x,Int_t y,Bool_t exclude)
find frame located int container at position x,y

Bool_t caseSensitive,Bool_t beginWith)
void AdjustPosition()
Move content to position of highlighted/activated frame
void LineLeft(Bool_t select)

void LineRight(Bool_t select)
Move current position one column right.
void LineUp(Bool_t select)
Make current position first line in window by scrolling up.
void LineDown(Bool_t select)
Move one line down.
void PageUp(Bool_t select)

void PageDown(Bool_t select)
Move position one page down.
void Home(Bool_t select)
Move to upper-left corner of container.
void End(Bool_t select)
