TGListBox, TGLBContainer, TGLBEntry and TGTextLBEntry
A listbox is a box, possibly with scrollbar, containing entries.
Currently entries are simple text strings (TGTextLBEntry).
A TGListBox looks a lot like a TGCanvas. It has a TGViewPort
containing a TGLBContainer which contains the entries and it also
has a vertical scrollbar which becomes visible if there are more
items than fit in the visible part of the container.
The TGListBox is user callable. The other classes are service
classes of the listbox.
Selecting an item in the listbox will generate the event:
kC_COMMAND, kCM_LISTBOX, listbox id, item id.
TGListBox(const TGWindow *p, Int_t id,
UInt_t options, ULong_t back) :
TGCompositeFrame(p, 10, 10, options, back)
Create a listbox.
~TGListBox()
Delete a listbox widget.
void InitListBox()
initiate the internal classes of a list box
void DrawBorder()
Draw borders of the list box widget.
void AddEntry(TGString *s, Int_t id)
Add entry with specified string and id to listbox. The id will be
used in the event processing routine when the item is selected.
The string will be adopted by the listbox.
void AddEntry(const char *s, Int_t id)
Add entry with specified string and id to listbox. The id will be
used in the event processing routine when the item is selected.
void AddEntry(TGLBEntry *lbe, TGLayoutHints *lhints)
Add specified TGLBEntry and TGLayoutHints to listbox. The
entry and layout will be adopted and later deleted by the listbox.
void AddEntrySort(TGString *s, Int_t id)
Add entry with specified string and id to listbox sorted by increasing id.
This sorting works proberly only if EntrySort functions are used to add
entries without mixing them with other add or insert functions. The id will be
used in the event processing routine when the item is selected.
The string will be adopted by the listbox.
void AddEntrySort(const char *s, Int_t id)
Add entry with specified string and id to listbox sorted by increasing id.
This sorting works proberly only if EntrySort functions are used to add
entries without mixing them with other add or insert functions. The id will be
used in the event processing routine when the item is selected.
void AddEntrySort(TGLBEntry *lbe, TGLayoutHints *lhints)
Add specified TGLBEntry and TGLayoutHints to listbox sorted by increasing id.
This sorting works proberly only if EntrySort functions are used to add
entries without mixing them with other add or insert functions. The
entry and layout will be adopted and later deleted by the listbox.
void InsertEntry(TGString *s, Int_t id, Int_t afterID)
Insert entry with specified string and id behind the entry with afterID.
The string will be adopted and later deleted by the listbox.
void InsertEntry(const char *s, Int_t id, Int_t afterID)
Insert entry with specified string and id behind the entry with afterID.
void InsertEntry(TGLBEntry *lbe, TGLayoutHints *lhints, int afterID)
Insert the specified TGLBEntry and layout hints behind afterID.
The entry and layout will be adopted and later deleted by the listbox.
void SetTopEntry(Int_t id)
Scroll the entry with id to the top of the listbox.
void Resize(UInt_t w, UInt_t h)
Resize the listbox widget. If fIntegralHeight is true make the height
an integral number of the maximum height of a single entry.
void MoveResize(Int_t x, Int_t y, UInt_t w, UInt_t h)
Move and resize the listbox widget.
TGDimension GetDefaultSize() const
Return default size of listbox widget.
void Layout()
Layout the listbox components.
Int_t GetSelected() const
Return id of selected listbox item.
void GetSelectedEntries(TList *selected)
Adds all selected entries (TGLBEntry) of the list box into
the list selected.
Bool_t ProcessMessage(Long_t msg, Long_t parm1, Long_t)
Process messages generated by the listbox container and forward
messages to the listbox message handling window.
