## Detailed Description

A wrap sizer lays out its items in a single line, like a box sizer -- as long as there is space available in that direction.

Once all available space in the primary direction has been used, a new line is added and items are added there.

So a wrap sizer has a primary orientation for adding items, and adds lines as needed in the secondary direction.

## Constructor & Destructor Documentation

wxWrapSizer::wxWrapSizer | ( | int | orient = `wxHORIZONTAL`,
|  | int | flags = `wxWRAPSIZER_DEFAULT_FLAGS` |
| ) |  |  |

Constructor for a wxWrapSizer.

orient determines the primary direction of the sizer (the most common case being `wxHORIZONTAL`). The flags parameter can be a combination of the values `wxEXTEND_LAST_ON_EACH_LINE` which will cause the last item on each line to use any remaining space on that line and `wxREMOVE_LEADING_SPACES` which removes any spacer elements from the beginning of a row.

Both of these flags are on by default.

## Member Function Documentation

virtual bool wxWrapSizer::InformFirstDirection | ( | int | direction,
|  | int | size,
|  | int | availableOtherDir |
| ) |  |  | `[virtual]`

Not used by an application.

This is the mechanism by which sizers can inform sub-items of the first determined size component. The sub-item can then better determine its size requirements.

Returns true if the information was used (and the sub-item min size was updated).

virtual bool wxWrapSizer::IsSpaceItem | ( | wxSizerItem * | item | ) | const`[protected, virtual]`

Can be overridden in the derived classes to treat some normal items as spacers.

This method is used to determine whether the given item should be considered to be a spacer for the purposes of `wxREMOVE_LEADING_SPACES` implementation. By default only returns true for the real spacers.
