Detailed Description

This class wraps gtkclist widget.

Signals

• select_row signal, emitted on selecting a list cell (or double clicking on extended selection mode). Selected property contains selected cell coordinates. Selected is set to VDKPoint(-1,-1) if no cell is selected.
• unselect_row_signal, emitted on unselecting a cell. Unselected property contains unselected cell coordinates.
• click_column_signal, emitted on clicking over a column titile, ColumnClicked() returns wich column was clicked.

Tip

Use Selected property property like this:

  VDKPoint p = list->Selected;
  int row = p.x;
  int col = p.y;
  // or simpler
  int row = list->Selected.Row();
  int col = list->Selected.Col();

Programming hints

Data contained into a VDKCustomList are organized as a list of tuples, a VDKTuple is a derived clas of an VDKArray<VDKString> that add equality and less-than operators (See vdkclist.h for further informations). You can access to data using [] operator on Tuples property like this:

  VDKTuple tuple = list->Tuples[j]; // access to j-th tuple
  VDKString s = list->Tuples[j][i]; // access to j-th,i-th string

Recall that Tuples is a read-only property, directly modifying a tuple does not reflect into the list widget, use VDKCustomList::UpdateRow() method at this end.

Examples

Into ./testvdk/testvdk.cc and .h

Member Data Documentation

SelectionProp VDKCustomList::Selected

Use this to know wich cell is selected or Selected.Row() or Selected.Col() <read-only>

SelectionProp VDKCustomList::Unselected

Use this to know wich cell is unselected or Unselected.Row() or Unselected.Col() <read-only>

TupleList VDKCustomList::Tuples

A tuple is a VDKArray<VDKString>. use this property to access data on row/cell basis like this:

    Tuple  tuple = list->Tuples[0];
    char * p = (char*) tuple[0];
    // or more simply
    char *p = (char*) list->Tuples[0][0];
