QdbtTabular

For more information on how to use the widget as a programmer see the online documentation.

Note: This project being moved over to sourceforge. Please look there for the latest updates.

• Extended selection modes
• Hide Column implemented (works with keyboardfocus traversal now)
• Cell Color Scheme, including common bg color for not editable cells
• Disable/Enable works
• Style Support
• According to the current mode of the tabular the selection may be cleared or set
• findRow() fixed (was broken when introducing cascaded headers)
• Focus-Movement is not controlled by the Tabular-Widget externally, so that it can be customized (e.g. locking the keyboard focus to a row of the widget temporarily)
• PageUp and PageDown are treated by the table-view now. Clicking a cell/Dragging now sets the keyboard-focus as well
• Editing is now being checked by a validator. The pattern for this editor is set for an entire column.
• Programmer-API a little more orthogonolized
• Update-Behaviour tidied up, so that autoUpdate is honoured throughout the tabular.
• Extension of TMAKE-Frojects for easier Windows-compilation
• To enable a 'clean' focus-traversal within the cells. each editing session emits 'cellEditDone()' now.
• ESC may be used to cancel the editing of the current cell, stopEdit() may be used to interrupt cell editing from within the programm.
• support for column-exchange and 'named' columns
• cascaded headers may be resized (same now as normal headers)
• table and header(s) got out of sync when deleting columns or using the middle mousebutton to autosize to header-element which caused the table to shift and the lower scrollbar to disappear

• A table cell may now addionally have a border
• Headers support now multiline texts, cascading headers (with grouping) added
• The style is customizable, so that it can looks like QListView
• The editCell()-method now accepts a new parameter which traverses the keyboard focus to the position being edited. Furthermore it may be called in response to the signal cellEdited() emitted by the tabular widget.

• Sven Meyer has provided me with the necessary changes to make the widget work with Qt-2.00. For this version Qt-2.00 is required!

Brief description:

Changed in version 0.31:

• Fixed pixmap inversion bug for non truecolor visuals.
• setPalette now works correctly (see example4).
• fixed an update problem that appears when using Qt 1.32

Changed in version 0.3:

• Added keyboard support.
• Fixed some problems with insert and removal of columns.
• Qt 1.31 is now required.

Changed in version 0.22:

• Fixed a bug in the resizing of the table.
• Changed the implementation of QdbtCellMatrix; adding rows is now faster.
• Moved the section widget to the public interface. The table header can now be modified by inheriting the QdbtSection widget.
• Improved the documentation, it is now automatically generated using doxygen.

Changed in version 0.21:

• Changed the QdbtLineEdit class. It now no longer is a modified copy of Troll Tech's sources (which was illegal, so if you have this version, please delete it), but a small class derived from QLineEdit.
  Qt 1.30 is now required.

New features in version 0.2:

• Cells can be edited; whether or not a cell may be edited can be controlled by the application programmer.
• Cells can be selected one row at a time, or individually. selection can also be disabled.
• A tooltip appears if the mouse is resting on a cell whose text is not completely visible. The tooltip will show the complete text.
• Pixmaps of a cell can now be above/below/to the left/to the right of the text.
• A lot of new member functions allowing to change the behavior of the table and its cells.
• 3 new examples demonstrating the new features. Qt look-a-like on-line documentation.
• Now uses tmake to generate the Makefiles.
• Tested with Qt version 1.30.

Features already in version 0.1:

• Multiple rows can be selected one by one, or by click-and-drag.
• The table has a heading; a section for each column. Each section is separated by a divider.
• Columns can be resized by click-and-dragging the divider; a slide bar is visible while dragging.
• Clicking the middle mouse button on a divider will resize the column, so that all cells in the column fit.
• Clicking on a section generates a signal.
• Automatic appearing/disappearing scrollbars.
• The table can be resized, empty rows and columns can be inserted.
• The font of the header and the cells can be set separately
• Texts that do not fit in a cell are truncated using dots (...)
• Fast cell access (Internally a 2D array of pointers to cells is used).
• Efficient and automatic widget updates.
• 100 % based on Qt components (QWidget/QFrame/QButton/QTableView).

Each cell in the table is a QdbtTabCell class, which has the following features. Each cell can

• have it's own foreground/background color
• have an optional text
• have an optional pixmap
• be left/right/center aligned
