@class wxSizer
|
|
|
|
wxSizer is the abstract base class used for laying out subwindows in a window.
|
|
You cannot use wxSizer directly; instead, you will have to use one of the sizer
|
|
classes derived from it. Currently there are wxBoxSizer, wxStaticBoxSizer,
|
|
wxGridSizer, wxFlexGridSizer, wxWrapSizer and wxGridBagSizer.
|
|
|
|
The layout algorithm used by sizers in wxWidgets is closely related to layout
|
|
in other GUI toolkits, such as Java's AWT, the GTK toolkit or the Qt toolkit.
|
|
It is based upon the idea of the individual subwindows reporting their minimal
|
|
required size and their ability to get stretched if the size of the parent window
|
|
has changed.
|
|
|
|
This will most often mean that the programmer does not set the original size of
|
|
a dialog in the beginning, rather the dialog will be assigned a sizer and this
|
|
sizer will be queried about the recommended size. The sizer in turn will query
|
|
its children, which can be normal windows, empty space or other sizers, so that
|
|
a hierarchy of sizers can be constructed. Note that wxSizer does not derive
|
|
from wxWindow and thus does not interfere with tab ordering and requires very little
|
|
resources compared to a real window on screen.
|
|
|
|
What makes sizers so well fitted for use in wxWidgets is the fact that every
|
|
control reports its own minimal size and the algorithm can handle differences in
|
|
font sizes or different window (dialog item) sizes on different platforms without
|
|
problems. If e.g. the standard font as well as the overall design of Motif widgets
|
|
requires more space than on Windows, the initial dialog size will automatically
|
|
be bigger on Motif than on Windows.
|
|
|
|
Sizers may also be used to control the layout of custom drawn items on the
|
|
window. The wxSizer::Add(), wxSizer::Insert(), and wxSizer::Prepend() functions
|
|
return a pointer to the newly added wxSizerItem.
|
|
Just add empty space of the desired size and attributes, and then use the
|
|
wxSizerItem::GetRect() method to determine where the drawing operations
|
|
should take place.
|
|
|
|
Please notice that sizers, like child windows, are owned by the library and
|
|
will be deleted by it which implies that they must be allocated on the heap.
|
|
However if you create a sizer and do not add it to another sizer or
|
|
window, the library wouldn't be able to delete such an orphan sizer and in
|
|
this, and only this, case it should be deleted explicitly.
|
|
|
|
@beginWxPythonOnly
|
|
If you wish to create a sizer class in wxPython you should
|
|
derive the class from @c wxPySizer in order to get Python-aware
|
|
capabilities for the various virtual methods.
|
|
@endWxPythonOnly
|
|
|
|
@section wxsizer_flags wxSizer flags
|
|
|
|
The "flag" argument accepted by wxSizeItem constructors and other
|
|
functions, e.g. wxSizer::Add(), is OR-combination of the following flags.
|
|
Two main behaviours are defined using these flags. One is the border around
|
|
a window: the border parameter determines the border width whereas the
|
|
flags given here determine which side(s) of the item that the border will
|
|
be added. The other flags determine how the sizer item behaves when the
|
|
space allotted to the sizer changes, and is somewhat dependent on the
|
|
specific kind of sizer used.
|
|
|
|
@beginDefList
|
|
@itemdef{wxTOP<br>
|
|
wxBOTTOM<br>
|
|
wxLEFT<br>
|
|
wxRIGHT<br>
|
|
wxALL,
|
|
These flags are used to specify which side(s) of the sizer item
|
|
the border width will apply to.}
|
|
@itemdef{wxEXPAND,
|
|
The item will be expanded to fill the space assigned to the item.}
|
|
@itemdef{wxSHAPED,
|
|
The item will be expanded as much as possible while also
|
|
maintaining its aspect ratio.}
|
|
@itemdef{wxFIXED_MINSIZE,
|
|
Normally wxSizers will use GetAdjustedBestSize() to determine what
|
|
the minimal size of window items should be, and will use that size
|
|
to calculate the layout. This allows layouts to adjust when an
|
|
item changes and its best size becomes different. If you would
|
|
rather have a window item stay the size it started with then use
|
|
@c wxFIXED_MINSIZE.}
|
|
@itemdef{wxRESERVE_SPACE_EVEN_IF_HIDDEN,
|
|
Normally wxSizers don't allocate space for hidden windows or other
|
|
items. This flag overrides this behavior so that sufficient space
|
|
is allocated for the window even if it isn't visible. This makes
|
|
it possible to dynamically show and hide controls without resizing
|
|
parent dialog, for example. (Available since 2.8.8.)}
|
|
@itemdef{wxALIGN_CENTER<br>
|
|
wxALIGN_CENTRE<br>
|
|
wxALIGN_LEFT<br>
|
|
wxALIGN_RIGHT<br>
|

|
|
wxALIGN_CENTRE_VERTICAL<br>
|
|
wxALIGN_CENTER_HORIZONTAL<br>
|
|
wxALIGN_CENTRE_HORIZONTAL,
|
|
The @c wxALIGN_* flags allow you to specify the alignment of the item
|
|
within the space allotted to it by the sizer, adjusted for the
|
|
border if any.}

This class creates button layouts which conform to the standard button spacing
|

|
|
(if such things exist). By using this class, you can ensure that all your
|
|
standard dialogs look correct on all major platforms. Currently it conforms to

|
the Windows, GTK+ and Mac OS X human interface guidelines.
|
|
|
|
When there aren't interface guidelines defined for a particular platform or
|
|
toolkit, wxStdDialogButtonSizer reverts to the Windows implementation.
|
|
|
|
To use this class, first add buttons to the sizer by calling
|
|
wxStdDialogButtonSizer::AddButton (or wxStdDialogButtonSizer::SetAffirmativeButton,
|
|
wxStdDialogButtonSizer::SetNegativeButton or wxStdDialogButtonSizer::SetCancelButton)
|
|
and then call Realize in order to create the actual button layout used.
|
|
Other than these special operations, this sizer works like any other sizer.
|
|
|
|
If you add a button with wxID_SAVE, on Mac OS X the button will be renamed to
|
|
"Save" and the wxID_NO button will be renamed to "Don't Save" in accordance
|
|
with the Mac OS X Human Interface Guidelines.

Container for sizer items flags providing readable names for them.
|

|
Normally, when you add an item to a sizer via wxSizer::Add, you have to
|
|
specify a lot of flags and parameters which can be unwieldy. This is where
|
|
wxSizerFlags comes in: it allows you to specify all parameters using the
|
|
named methods instead. For example, instead of
|
|
|
|
@code
|
|
sizer->Add(ctrl, 0, wxEXPAND | wxALL, 10);
|
|
@endcode
|
|
|
|
you can now write
|
|
|
|
@code
|
|
sizer->Add(ctrl, wxSizerFlags().Expand().Border(wxALL, 10));
|
|
@endcode
|
|
|
|
This is more readable and also allows you to create wxSizerFlags objects which
|
|
can be reused for several sizer items.
|
|
|
|
@code
|
|
wxSizerFlags flagsExpand(1);
|
|
flagsExpand.Expand().Border(wxALL, 10);
|
|
|
|
sizer->Add(ctrl1, flagsExpand);
|
|
sizer->Add(ctrl2, flagsExpand);
|
|
@endcode
|
|
|
|
Note that by specification, all methods of wxSizerFlags return the wxSizerFlags
|
|
object itself to allowing chaining multiple methods calls like in the examples
|
|
above.

A flex grid sizer is a sizer which lays out its children in a two-dimensional

table with all table fields in one row having the same height and all fields

in one column having the same width, but all rows or all columns are not

Since wxWidgets 2.5.0, wxFlexGridSizer can also size items equally in one

direction but unequally ("flexibly") in the other. If the sizer is only

flexible in one direction (this can be changed using wxFlexGridSizer::SetFlexibleDirection),

it needs to be decided how the sizer should grow in the other ("non-flexible")
|
|
direction in order to fill the available space.
|

The wxFlexGridSizer::SetNonFlexibleGrowMode() method serves this purpose.
