\section{wxGrid classes overview}\label{gridoverview}
|
||
|
|
|
||
|
|
wxGrid is a class for displaying and editing tabular information.
|
||
|
|
|
||
|
|
To use wxGrid, include the wxgrid.h header file and link with the
|
||
|
|
wxGrid library. Create a wxGrid object, or, if you need to override
|
||
|
|
some default behaviour, create an object of a class derived from wxGrid.
|
||
|
|
You need to call CreateGrid before there are any cells in the grid.
|
||
|
|
|
||
|
|
All row and column positions start from zero, and dimensions are in pixels.
|
||
|
|
|
||
|
|
If you make changes to row or column dimensions, call UpdateDimensions and
|
||
|
|
then AdjustScrollbars. If you make changes to the grid appearance (such as
|
||
|
|
a change of cell background colour or font), call Refresh for the changes
|
||
|
|
to be shown.
|
||
|
|
|
||
|
|
\subsection{Example}
|
||
|
|
|
||
|
|
The following fragment is taken from the file samples/grid/test.cpp. Note the
|
||
|
|
call to UpdateDimensions, which is required if the application
|
||
|
|
has changed any dimensions such as column width or row height.
|
||
|
|
You may also need to call AdjustScrollbars. In this case, AdjustScrollbars
|
||
|
|
isn't necessary because it will be called by wxGrid::OnSize which is invoked
|
||
|
|
when the window is first displayed.
|
||
|
|
|
||
|
|
\begin{verbatim}
|
||
|
|
// Make a grid
|
||
|
|
frame->grid = new wxGrid(frame, 0, 0, 400, 400);
|
||
|
|
|
||
|
|
frame->grid->CreateGrid(10, 8);
|
||
|
|
frame->grid->SetColumnWidth(3, 200);
|
||
|
|
frame->grid->SetRowHeight(4, 45);
|
||
|
|
frame->grid->SetCellValue("First cell", 0, 0);
|
||
|
|
frame->grid->SetCellValue("Another cell", 1, 1);
|
||
|
|
frame->grid->SetCellValue("Yet another cell", 2, 2);
|
||
|
|
frame->grid->SetCellTextFont(wxTheFontList->FindOrCreateFont(12, wxROMAN, wxITALIC, wxNORMAL), 0, 0);
|
||
|
|
frame->grid->SetCellTextColour(*wxRED, 1, 1);
|
||
|
|
frame->grid->SetCellBackgroundColour(*wxCYAN, 2, 2);
|
||
|
|
frame->grid->UpdateDimensions();
|
||
|
|
\end{verbatim}
