Detailed Description

The wxSizerItem class is used to track the position, size and other attributes of each item managed by a wxSizer.

It is not usually necessary to use this class because the sizer elements can also be identified by their positions or window or sizer pointers but sometimes it may be more convenient to use it directly.

Library:  wxCore

Member Function Documentation

void wxSizerItem::AssignSizer ( wxSizer sizer)

Set the sizer tracked by this item.

Old sizer, if any, is deleted.

void wxSizerItem::AssignSpacer ( int  w,
int  h 
)

Set the size of the spacer tracked by this item.

Old spacer, if any, is deleted.

void wxSizerItem::AssignSpacer ( const wxSize size)

Set the size of the spacer tracked by this item.

Old spacer, if any, is deleted.

void wxSizerItem::AssignWindow ( wxWindow window)

Set the window to be tracked by this item.

The old window isn't deleted as it is now owned by the sizer item.

virtual wxSize wxSizerItem::CalcMin ( ) [virtual]

Calculates the minimum desired size for the item, including any space needed by borders.

virtual void wxSizerItem::DeleteWindows ( ) [virtual]

Destroy the window or the windows in a subsizer, depending on the type of item.

void wxSizerItem::DetachSizer ( )

Enable deleting the SizerItem without destroying the contained sizer.

int wxSizerItem::GetBorder ( ) const

Return the border attribute.

int wxSizerItem::GetFlag ( ) const

Return the flags attribute.

See wxSizer flags list for details.

int wxSizerItem::GetId ( ) const

Return the numeric id of wxSizerItem, or wxID_NONE if the id has not been set.

wxSize wxSizerItem::GetMinSize ( ) const

Get the minimum size needed for the item.

wxPoint wxSizerItem::GetPosition ( ) const

What is the current position of the item, as set in the last Layout.

int wxSizerItem::GetProportion ( ) const

Get the proportion item attribute.

float wxSizerItem::GetRatio ( ) const

Get the ration item attribute.

virtual wxRect wxSizerItem::GetRect ( ) [virtual]

Get the rectangle of the item on the parent window, excluding borders.

virtual wxSize wxSizerItem::GetSize ( ) const [virtual]

Get the current size of the item, as set in the last Layout.

wxSizer* wxSizerItem::GetSizer ( ) const

If this item is tracking a sizer, return it.

NULL otherwise.

NULL otherwise.

bool wxSizerItem::IsShown ( ) const

Returns true if this item is a window or a spacer and it is shown or if this item is a sizer and not all of its elements are hidden.

In other words, for sizer items, all of the child elements must be hidden for the sizer itself to be considered hidden.

As an exception, if the wxRESERVE_SPACE_EVEN_IF_HIDDEN flag was used for this sizer item, then IsShown() always returns true for it (see wxSizerFlags::ReserveSpaceEvenIfHidden()).

Set the proportion item attribute.

Set the ratio item attribute.

Set the ratio item attribute.

Deprecated:
This function does not free the old sizer which may result in memory leaks, use AssignSizer() which does free it instead.
void wxSizerItem::SetSpacer ( const wxSize size)

Set the size of the spacer tracked by this item.

Deprecated:
This function does not free the old spacer which may result in memory leaks, use AssignSpacer() which does free it instead.

Todo:
provide deprecation description
