Gridviews

Gridviews provide a mechanism for managing row- and column-based views, such as those used in spreadsheets and scrolling lists. A gridview contains a number of cells, organized in variably sized rows and columns, and has methods for modifying the width and height of a cell, for selecting a cell, for retrieving or setting the content of a cell, and for other cell-specific operations.

In the UGridView unit, MacApp defines a number of classes for working with gridviews, including the following:

TGridView

The TGridView class displays a one- or two-dimensional grid of cells. The cells can contain text, pictures, or other subviews.

TTextGridView

The TTextGridView class displays a one- or two- dimensional grid of cells containing text only.

TTextListView

The TTextListView class displays a one-dimensional grid of cells containing text only.

TCellSelectCommand

The TCellSelectCommand class selects one or more cells in a gridview.

TColSelectCommand

The TColSelectCommand class selects one or more entire columns of cells in a gridview.

TRowSelectCommand

The TRowSelectCommand class selects one or more entire rows of cells in a gridview.

The Calc sample application demonstrates the use of multiple gridviews to create a spreadsheet.
