Detailed Description

QicsTableGrid is a private widget used internally by the QicsTable widget. The grid widget is responsible for laying out the cells based on the size of the widget and based on various properties that are stored in the QicsStyleManager. The grid does not actually draw anyting, rather it determines where each cell should be drawn and calls the appropriate cell display object for the actual display of the widget.

Most users of the QicsTable product should not need to create or modify QicsTableGrid objects directly. The QicsTable widget automatically creates the necessary grid objects when needed. One instance where a user may need to modify a grid is to change the mouse and/or keyboard behavior of the grids.

The grid widget is also largely responsible for managing user interaction with the table. The grid handles mouse and keyboard events on its window, and performs the appropriate action (selection and traversal, primarily).

Member Typedef Documentation

typedef QicsTableGrid*(* QicsTableGrid::Foundry)(QWidget *w, QicsGridInfo &info, int top_row, int left_column)

Foundry method to create new instances of QicsTableGrid (or a subclass of QicsTableGrid). Subclasses of QicsTableGrid should implement a similar method. Methods of this type can be passed to a QicsTable constructor in order to create custom grids.

typedef QicsTableGrid*(* QicsTableGrid::FoundryWithKey)(QWidget *w, QicsGridInfo &info, int top_row, int left_column, void *key)

Internal foundry method to create new instances of QicsTableGrid (or a subclass of QicsTableGrid). Methods of this type can be passed to a QicsTable constructor in order to create custom grids. A pointer to a previously provided "key" is passed as a parameter. This typedef is not exposed as part of the public API. It has been added because it's necessary for the Python bindings.

Reimplemented from QicsGrid.

int QicsScreenGrid::lastPageStartRow ( void ) [inherited]

Returns the index of the row that would be displayed at the top of the grid if the last displayable cell was placed at the bottom right of the grid. This value is used by the QicsTable to set the appropriate values on the table's scrollbars.

int QicsScreenGrid::lastPageStartColumn ( void ) [inherited]

Returns the index of the column that would be displayed at the left of the grid if the last displayable cell was placed at the bottom right of the grid. This value is used by the QicsTable to set the appropriate values on the table's scrollbars.

	)			const `[inherited]`

Computes row and column values (given the current topRow and leftColumn) for the window coordinates (x, y ), and returns those values as a QicsICell. If the coordinates do not correspond to a cell, behavior is dependent on the value of nearest. If nearest is true, this method will return the nearest cell to the coordinates. If it is false, it will return an invalid cell.
