Functions for wxGridBagSizer class

A wxSizer that can lay out items in a virtual grid like a wxFlexGridSizer but in this case explicit positioning of the items is allowed using wxGBPosition (not implemented in wx), and items can optionally span more than one row and/or column using wxGBSpan (not implemented in wx).

This class is derived (and can use functions) from: wxFlexGridSizer wxGridSizer wxSizer

wxWidgets docs: wxGridBagSizer

Summary

Functions

Adds the given item to the given position.

Adds a spacer to the given position.

Called when the managed size of the sizer is needed or when layout needs done.

Look at all items and see if any intersect (or would overlap) the given item.

Destroys the object.

Find the sizer item for the given window or subsizer, returns NULL if not found.

Return the sizer item located at the point given in pt, or NULL if there is no item at that point.

Return the sizer item for the given grid cell, or NULL if there is no item at that position.

Return the sizer item that has a matching user data (it only compares pointer values) or NULL if not found.

Get the size of the specified cell, including hgap and vgap.

Get the size used for cells in the grid with no item.

Constructor, with optional parameters to specify the gap between the rows and columns.

Set the size used for cells in the grid with no item.
