Detailed Description

The basic idea behind a box sizer is that windows will most often be laid out in rather simple basic geometry, typically in a row or a column or several hierarchies of either.

Constructor & Destructor Documentation

◆ wxBoxSizer()

wxBoxSizer::wxBoxSizer ( int  orient)

Constructor for a wxBoxSizer.

orient may be either of wxVERTICAL or wxHORIZONTAL for creating either a column sizer or a row sizer.

Member Function Documentation

◆ AddSpacer()

virtual wxSizerItem* wxBoxSizer::AddSpacer ( int  size)
virtual

Adds non-stretchable space to the main orientation of the sizer only.

More readable way of calling:

if ( wxBoxSizer::IsVertical() )
{
wxBoxSizer::Add(0, size, 0).
}
else
{
wxBoxSizer::Add(size, 0, 0).
}
wxSizerItem * Add(wxWindow *window, const wxSizerFlags &flags)
Appends a child to the sizer.

Reimplemented from wxSizer.

◆ CalcMin()

virtual wxSize wxBoxSizer::CalcMin ( )
virtual

Implements the calculation of a box sizer's minimal.

It is used internally only and must not be called by the user. Documented for information.

Implements wxSizer.

Reimplemented in wxWrapSizer, wxStaticBoxSizer, and wxStdDialogButtonSizer.

◆ GetOrientation()

int wxBoxSizer::GetOrientation ( ) const

Returns the orientation of the box sizer, either wxVERTICAL or wxHORIZONTAL.

◆ RepositionChildren()

virtual void wxBoxSizer::RepositionChildren ( const wxSize minSize)
virtual

Method which must be overridden in the derived sizer classes.

The implementation should reposition the children using the current total size available to the sizer (m_size) and the size computed by the last call to CalcMin().

Since
3.1.3, before this version RecalcSizes() method not taking any arguments had to be overridden in the derived classes instead.

Implements wxSizer.

Reimplemented in wxWrapSizer, wxStaticBoxSizer, and wxStdDialogButtonSizer.

◆ SetOrientation()

void wxBoxSizer::SetOrientation ( int  orient)

Sets the orientation of the box sizer, either wxVERTICAL or wxHORIZONTAL.
