wx.SizerFlags¶

Container for sizer items flags providing readable names for them.

Normally, when you add an item to a sizer via wx.Sizer.Add , you have to specify a lot of flags and parameters which can be unwieldy. This is where wx.SizerFlags comes in: it allows you to specify all parameters using the named methods instead. For example, instead of

sizer.Add(ctrl, 0, wx.EXPAND | wx.ALL, 10)

you can now write

sizer.Add(ctrl, wx.SizerFlags().Expand().Border(wx.ALL, 10))

This is more readable and also allows you to create wx.SizerFlags objects which can be reused for several sizer items.

flagsExpand = wx.SizerFlags(1)
flagsExpand.Expand().Border(wx.ALL, 10)

sizer.Add(ctrl1, flagsExpand)
sizer.Add(ctrl2, flagsExpand)

Note that by specification, all methods of wx.SizerFlags return the wx.SizerFlags object itself to allowing chaining multiple methods calls like in the examples above.

Methods Summary¶

`__init__`	Creates the wx.Sizer with the proportion specified by proportion.
`Align`	Sets the alignment of this wx.SizerFlags to align.
`Border`	Sets the wx.SizerFlags to have a border of a number of pixels specified by borderinpixels with the directions specified by direction.
`Bottom`	Aligns the object to the bottom, similar for `Align(wxALIGN_BOTTOM)` .
`Center`	Sets the object of the wx.SizerFlags to center itself in the area it is given.
`Centre`	`wx.Center` for people with the other dialect of English.
`DoubleBorder`	Sets the border in the given direction having twice the default border size.
`DoubleHorzBorder`	Sets the border in left and right directions having twice the default border size.
`Expand`	Sets the object of the wx.SizerFlags to expand to fill as much area as it can.
`FixedMinSize`	Set the `FIXED_MINSIZE` flag which indicates that the initial size of the window should be also set as its minimal size.
`GetDefaultBorder`	Returns the border used by default in wx.Border method.
`Left`	Aligns the object to the left, similar for `Align(wxALIGN_LEFT)` .
`Proportion`	Sets the proportion of this wx.SizerFlags to proportion.
`ReserveSpaceEvenIfHidden`	Set the `RESERVE_SPACE_EVEN_IF_HIDDEN` flag.
`Right`	Aligns the object to the right, similar for `Align(wxALIGN_RIGHT)` .
`Shaped`	Set the `_SHAPED` flag which indicates that the elements should always keep the fixed width to height ratio equal to its original value.
`Top`	Aligns the object to the top, similar for `Align(wxALIGN_TOP)` .
`TripleBorder`	Sets the border in the given direction having thrice the default border size.

Class API¶

class wx.SizerFlags(object)¶

Possible constructors:

SizerFlags(proportion=0)

Container for sizer items flags providing readable names for them.

Methods¶

__init__(self, proportion=0)¶

Creates the wx.Sizer with the proportion specified by proportion.

Parameters:	proportion (int) –

Align(self, alignment)¶

Sets the alignment of this wx.SizerFlags to align.

This method replaces the previously set alignment with the specified one.

Parameters:	alignment (int) – Combination of `ALIGN_XXX` bit masks.
Return type:	wx.SizerFlags

wx.Top , wx.Left , wx.Right , wx.Bottom , wx.Centre

Border(self, *args, **kw)¶

Overloaded Implementations:

Border (self, direction, borderinpixels)

Sets the wx.SizerFlags to have a border of a number of pixels specified by borderinpixels with the directions specified by direction.

Parameters:	direction (int) – borderinpixels (int) –
Return type:	wx.SizerFlags

Border (self, direction=ALL)

Sets the wx.SizerFlags to have a border with size as returned by GetDefaultBorder .

Parameters:	direction (int) – Direction(s) to apply the border in.
Return type:	wx.SizerFlags

Bottom(self)¶

Aligns the object to the bottom, similar for Align(wxALIGN_BOTTOM) .

Unlike Align , this method doesn’t change the horizontal alignment of the item.

Return type:	wx.SizerFlags

Center(self)¶

Sets the object of the wx.SizerFlags to center itself in the area it is given.

Return type:	wx.SizerFlags

Centre(self)¶

wx.Center for people with the other dialect of English.

Return type:	wx.SizerFlags

DoubleBorder(self, direction=ALL)¶

Sets the border in the given direction having twice the default border size.

Parameters:	direction (int) –
Return type:	wx.SizerFlags

DoubleHorzBorder(self)¶

Sets the border in left and right directions having twice the default border size.

Return type:	wx.SizerFlags

Expand(self)¶

Sets the object of the wx.SizerFlags to expand to fill as much area as it can.

Return type:	wx.SizerFlags

FixedMinSize(self)¶

Set the FIXED_MINSIZE flag which indicates that the initial size of the window should be also set as its minimal size.

Return type:	wx.SizerFlags

static GetDefaultBorder()¶

Returns the border used by default in wx.Border method.

Return type:	int

Left(self)¶

Aligns the object to the left, similar for Align(wxALIGN_LEFT) .

Unlike Align , this method doesn’t change the vertical alignment of the item.

Return type:	wx.SizerFlags

Proportion(self, proportion)¶

Sets the proportion of this wx.SizerFlags to proportion.

Parameters:	proportion (int) –
Return type:	wx.SizerFlags

ReserveSpaceEvenIfHidden(self)¶

Set the RESERVE_SPACE_EVEN_IF_HIDDEN flag.

Normally Sizers don’t allocate space for hidden windows or other items. This flag overrides this behaviour 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.

Return type:	wx.SizerFlags

New in version 2.8.8.

Right(self)¶

Aligns the object to the right, similar for Align(wxALIGN_RIGHT) .

Unlike Align , this method doesn’t change the vertical alignment of the item.

Return type:	wx.SizerFlags

Shaped(self)¶

Set the _SHAPED flag which indicates that the elements should always keep the fixed width to height ratio equal to its original value.

Return type:	wx.SizerFlags

Top(self)¶

Aligns the object to the top, similar for Align(wxALIGN_TOP) .

Unlike Align , this method doesn’t change the horizontal alignment of the item.

Return type:	wx.SizerFlags

TripleBorder(self, direction=ALL)¶

Sets the border in the given direction having thrice the default border size.

Parameters:	direction (int) –
Return type:	wx.SizerFlags
