# Package Gtk.Extra.Sheet

A Gtk_Sheet is a table like the one you can find in most spreadsheets. Each cell can contain some text or any kind of widgets.

- Gtk.Extra.Sheet Signals
- Gtk.Extra.Sheet Types
- Gtk.Extra.Sheet Subprograms

## Widget Hierarchy

    Gtk_Object                    (see section Package Gtk.Object)
       \___ Gtk_Widget            (see section Package Gtk.Widget)
          \___ Gtk_Container      (see section Package Gtk.Container)
             \___ Gtk_Sheet       (see section Package Gtk.Extra.Sheet)

## Signals

- "activate" function Handler (Sheet : access Gtk_Sheet_Record'Class;
  Row : Gint;
  Column : Gint)
  return Boolean;
  Emitted when the user wants to activate a specific cell. The callback should return True if the cell can be activated, False otherwise. See the subprogram Activate_Cell.
- "changed" procedure Handler (Sheet : access Gtk_Sheet_Record'Class;
  Row : Gint;
  Column : Gint);
  Emitted when the content of the cell is modified (either the text itself, or its properties, alignment,...) A value of -1 for Row or Column means the row title, the column title, or their intersection.
- "clear_cell" procedure Handler (Sheet : access Gtk_Sheet_Record'Class;
  Row : Gint;
  Column : Gint);
  Emitted when the content of the cell has been deleted (the text is now the empty string).
- "clip_range" procedure Handler (Sheet : access Gtk_Sheet_Record'Class;
  Clip_Range : Gtk_Sheet_Range);
  Emitted when the clip area is set to a new value.
- "deactivate" function Handler (Sheet : access Gtk_Sheet_Record'Class;
  Row : Gint;
  Column : Gint)
  return Boolean;
  Emitted when the user wants to deactivate a specific cell. The callback should return True if the cell can be deactivated, False otherwise. See the subprogram Deactivate_Cell.
- "move_range" procedure Handler (Sheet : access Gtk_Sheet_Record'Class;
  Old_Range : Gtk_Sheet_Range;
  New_Range : Gtk_Sheet_Range);
  Emitted when the current range of selected cell is moved (ie the top-left cell is changed, but the size is not modified).
- "new_column_width" procedure Handler (Sheet : access Gtk_Sheet_Record'Class;
  Column : Gint;
  Width : Guint);
  Emitted whenever the width of the column is changed, either by the user or automatically if the cells should automatically resize themselves depending on their contents).
- "new_row_height" procedure Handler (Sheet : access Gtk_Sheet_Record'Class;
  Row : Gint;
  Height : Guint);
  Emitted whenever the height of the row is changed.
- "resize_range" procedure Handler (Sheet : access Gtk_Sheet_Record'Class;
  Old_Range : Gtk_Sheet_Range;
  New_Range : Gtk_Sheet_Range);
  Emitted when the current range of selected cell is resized (ie new cells are added to it or removed from it).
- "select_column" procedure Handler (Sheet : access Gtk_Sheet_Record'Class;
  Column : Gint);
  Emitted when a new column is selected.
- "select_range" procedure Handler (Sheet : access Gtk_Sheet_Record'Class;
  The_Range : Gtk_Sheet_Range);
  Emitted when a new range of cells is selected.
- "select_row" procedure Handler (Sheet : access Gtk_Sheet_Record'Class;
  Row : Gint);
  Emitted when a new row is selected.
- "set_cell" procedure Handler (Sheet : access Gtk_Sheet_Record'Class;
  Row : Gint;
  Column : Gint);
  Emitted from Hide_Active_Cell, when the cell is non-empty. ???
- "set_scroll_adjustments" procedure Handler (Sheet : access Gtk_Sheet_Record'Class;
  Hadj : Gtk_Adjustement;
  Vadj : Gtk_Adjustment);
  Emitted when the adjustments used to indicate which area of the sheet is visible are set or changed. This is not called when their value is changed, only when a new one is set.
- "traverse" function Handler (Sheet : access Gtk_Sheet_Record'Class;
  Row : Gint;
  Column : Gint;
  New_Row : Gint_Access;
  New_Column : Gint_Access)
  return Boolean;
  Emitted when the user wants to make a new cell active. The coordinates of the currently active cell are passed in (Row, Column), the coordinates of the cell that the user would like to select are passed in (New_Row, New_Column). The callback can modify the new values, and should return True if the new coordinates are accepted, False if the selection should be refused.

| Mask that indicates which borders should be visible in a cell.
    type Gtk_Sheet_Child is new Gdk.C_Proxy;

### Children
A Gtk_Sheet can contain some children, attached to some specific cells.

       Widget             : access Gtk.Widget.Gtk_Widget_Record'Class;
       X                  : in     Gint;
       Y                  : in     Gint);
| Put a new child at a specific location (in pixels) in the sheet.
    procedure Attach
      (Sheet              : access Gtk_Sheet_Record;
       Widget             : access Gtk.Widget.Gtk_Widget_Record'Class;
       Row                : in     Gint;

    procedure Move_Child
      (Sheet              : access Gtk_Sheet_Record;
       Widget             : access Gtk.Widget.Gtk_Widget_Record'Class;

       Y                  : in     Gint);
| Move a child of the table to a specific location in pixels. A warning is printed if Widget is not already a child of Sheet.
    function Get_Child_At
      (Sheet              : access Gtk_Sheet_Record;
       Row                : in     Gint;

       Y_Align            : in     Gfloat);
| Attach a new button in the row or column title. One of Row or Col must be negative (but only one). This can be used to modify the standard buttons that appear at the top of each column, or on the left of each row.
### Links / User_Data
You can associate any kind of data with a cell, just like you can associate user_data with all the widgets. Note that this uses a generic package, which must be instantiated at library level since it has internal clean up functions.
    procedure Link_Cell
      (Sheet              : access Gtk_Sheet_Record;
       Row                : in     Gint;
       Col                : in     Gint;
       Link               : in     Data_Type);
| Associate some user specific data with a given cell.
    function Get_Link
      (Sheet              : access Gtk_Sheet_Record;
       Row                : in     Gint;
       Col                : in     Gint)
       return Data_Type_Access;
| Return the user data associated with the cell. null is returned if the cell has no user data.
    procedure Remove_Link
      (Sheet              : access Gtk_Sheet_Record;
       Row                : in     Gint;
       Col                : in     Gint);
| Delete the user data associated with the cell.
### Flags
Some flags are defined for this widget. You can not access them through the usual interface in Gtk.Object.Flag_Is_Set since this widget is not part of the standard gtk+ packages. Instead, use the functions below. "Is_Locked" Set if the cells are editable "Is_Frozen" Set if the sheet is temporary frozen, ie does not redisplay itself after each modification. See the subprograms Freeze and Thaw. "In_Xdrag" Set while a column is being dynamically resized by the user. "In_Ydrag" Set while a row is being dynamically resized by the user. "In_Drag" Set while the active cell's is being dragged. "In_Selection" Set while the user is selecting a block of cells. "In_Resize" Set while the sheet itself is being dynamically resized by the user. "In_Clip" See the subprograms Clip_Range and Unclip_Range. "Row_Frozen" Set when the user can not dynamically resize the rows. "Column_Frozen" Set when the user can not dynamically resize the columns. "Auto_Resize" Set when the columns automatically resize themselves when their content is longer than their width. "Clip_Text" Set when the text contained in the cells is automatically clipped to their width. "Row_Titles_Visible" Set when a special column is added to the left to show the title of the rows. "Column_Titles_Visible" Set when a special row is added at the top to show the title of the columns. "Auto_Scroll" Set when the sheet should automatically scroll to show the active cell at all times. "Justify_Entry" Set when the justification attribute for entries should be taken into account
    function Sheet_Flag_Is_Set
      (Sheet              : access Gtk_Sheet_Record;
       Flag               :        Guint16)
       return Boolean;
| Test whether one of the flags for a Gtk_Sheet widget or its children is set. This can only be used for the flags defined in the Gtk.Extra.Gtk_Sheet package.
    procedure Sheet_Set_Flags
      (Sheet              : access Gtk_Sheet_Record;
       Flags              :        Guint16);
| Set the flags for a Gtk_Sheet widget or its children. Note that the flags currently set are not touched by this function. This can only be used for the flags defined in the Gtk.Extra.Gtk_Sheet package.
    procedure Sheet_Unset_Flags
      (Sheet              : access Gtk_Sheet_Record;
       Flags              :        Guint16);
| Unset the flags in the widget.
