Detailed Description

One item/line in a KVListView window.

Example of use

KVListView takes a list of objects (TObject or derived class) and presents them as a list of items with different data for each object presented in separate columns. The user specifies the base-class of the objects to display, the number of columns, and the data to be presented in each column. The example in the figure shown above was generated by the following:

   lvRuns = new KVListView(KVDBRunClass(), cfRuns, 500, 250); //create list view for KVDBRun objects. 'cfRuns' is pointer to GUI frame containing the list.
   lvRuns->SetDataColumns(4); //set number of columns to 4

   lvRuns->SetDataColumn(0, "Run", "GetNumber");       //by default, the data presented in a column with title "Toto" will be retrieved
   lvRuns->SetDataColumn(1, "Events", "", kTextRight); //from each object by calling the "GetToto" method of the class given to the KVListView ctor.
   lvRuns->SetDataColumn(2, "Date", "GetDatime");      //in case the "getter" method has a non-standard name, it can be given explicitly.

   lvRuns->GetDataColumn(2)->SetIsDateTime();//some special treatment is afforded to date/time data. see method doc.
   lvRuns->SetDataColumn(3, "Comments", "", kTextLeft);// specify text alignment for data


   lvRuns->ActivateSortButtons();//when clicking a column header, the list is sorted according to that column's data.
   ...                           //clicking a second time the same column sorts objects in the opposite sense.

To display objects, put them in a TList and call

   lvRuns->Display( pointer_to_TList );

Items in the list can be selected using either:

single left click (single object selection),
CTRL+left-click (selection of multiple non-neighbouring objects),
or SHIFT+left-click (selection of multiple & neighbouring objects)

When the selection changes, the KVListView emits the

SelectionChanged()

signal.
The list of the currently selected objects can be retrieved with the method

GetSelectedItems()

, which returns a TList of the currently selected KVLVEntry objects, each one's name corresponds to the value displayed in the first column of the list view.
Double-left-clicking an object will execute the

Browse()

method of the object. This method is defined for all TObjects, it can be overridden in derived classes in order to do something interesting and/or useful.
Right-clicking an object opens the context menu of the object, allowing the usual interaction with objects as in TBrower, TCanvas, etc.

Draw list view item in other window. List view item is placed and layout in the container frame, but is drawn in viewport.

This is a line for line copy of TGLVEntry::DrawCopy from ROOT v5.22/00, but we alternate the background colour between white and light grey, in order to make the list easier to read.

If fColoured=kTRUE (i.e. if entry has a valid GetLVEntryColor method which returns a recognised color), the requested background color is used

Reimplemented from TGFrame.
