Detailed Description

An Fl_ColumnManager controlls the row sorting of an Fl_Browser.

The class is designed to manage the row sorting of the text in an Fl_Browser. Depressing any column button will cause the rows to be sorted by the text in that column. It uses the column_widths() of the associated browser to draw itself. These widths can be changed interactively.

Constructor & Destructor Documentation

Fl_ColumnManager::Fl_ColumnManager (  int    x, int    y, int    w, int    h, const char *    label = NULL )

Standard fltk constructor. Defers associating the controlled browser. Sets the sorting column to none (-1).

Member Function Documentation

void Fl_ColumnManager::click_control (  int    c, int    X, int    Y, int    W, int    H )  [protected]

Process a click for a specified control button, it's box must be passed in. Excludes 3 pixels at the ends of the control button for resizing them.

void Fl_ColumnManager::drag_control (  int    c, int    X, int    Y, int    W, int    H )  [protected]

Process a drag for a specified divider, the lefthand control button's box must be passed in. Resizing via dragging requires the mouse be within 3 pixels of the control button dividers.

void Fl_ColumnManager::draw (    )

Response to fltk draw requests. Uses the common utility for processing each column.

void Fl_ColumnManager::draw_control (  int    c, int    X, int    Y, int    W, int    H )  [protected]

Draw control button for the specified column, it's box must be passed in. Could be modified to draw a label in the control button.

void Fl_ColumnManager::for_each_column (  void(Fl_ColumnManager::*    action)(int col, int, int, int, int) )  [protected]

Common utility for processing each column. Each column's box is calculated and then the action called for it.

int Fl_ColumnManager::handle (  int    event )

Process click and drag events. FL_PUSH checks for a click on each column control. FL_DRAG tries to drag the column divider, if close enough (+/-3 pixels).

void Fl_ColumnManager::scrollbar_callback (  Fl_Widget *    s, void *    cm )  [static, protected]

Replacement callback for the browser's hscrollbar. Performs the same task as the fltk 1.1.4 callback does, but also forces the control manager to redraw.

void Fl_ColumnManager::set_browser (  Fl_Browser *    b )

Identify the associated browser and establish a link with the it. In addition to identifying the associated browser, the callback for the browser's hscrollbar is changed. This also sets the hscrollbar's user_data to point to this column manager.

void Fl_ColumnManager::update (    )

Force sorting and redraw of controller. This should be called whenever the sorting needs to be done or the column widths have been changed directly through the browser.
