class Layoutf(wx.LayoutConstraints):
|
|
"""
|
|
The class Layoutf(wxLayoutConstraints) presents a simplification
|
|
of the wxLayoutConstraints syntax. The name Layoutf is choosen
|
|
because of the similarity with C's printf function.
|
|
|
|
Quick Example::
|
|
|
|
lc = Layoutf('t=t#1;l=r10#2;r!100;h%h50#1', (self, self.panel))
|
|
|
|
|
|
is equivalent to::
|
|
|
|
lc = wx.LayoutContraints()
|
|
lc.top.SameAs(self, wx.Top)
|
|
lc.left.SameAs(self.panel, wx.Right, 10)
|
|
lc.right.Absolute(100)
|
|
lc.height.PercentOf(self, wx.Height, 50)
|
|
|
|
|
|
Usage:
|
|
|
|
You can give a constraint string to the Layoutf constructor,
|
|
or use the 'pack' method. The following are equivalent::
|
|
|
|
lc = Layoutf('t=t#1;l=r#2;r!100;h%h50#1', (self, self.panel))
|
|
|
|
|
|
and::
|
|
|
|
lc = Layoutf()
|
|
lc.pack('t=t#1;l=r#2;r!100;h%h50#1', (self, self.panel))
|
|
|
|
|
|
Besides 'pack' there's also 'debug_pack' which does not set
|
|
constraints, but prints traditional wxLayoutConstraint calls to
|
|
stdout.
|
|
|
|
The calls to the Layoutf constructor and pack methods have
|
|
the following argument list:
|
|
|
|
`(constraint_string, objects_tuple)`
|
|
|
|
|
|
Constraint String syntax:
|
|
|
|
Constraint directives are separated by semi-colons. You
|
|
generally (always?) need four directives to completely describe a
|
|
subwindow's location.
|
|
|
|
A single directive has either of the following forms:
|
|
|
|
1. <own attribute><compare operation>[numerical argument]
|
|
for example ``r!100`` -> lc.right.Absolute(100) )
|
|
and ``w*`` -> lc.width.AsIs()
|
|
|
|
2. <own attribute><compare operation>[numerical argument]
|
|
#<compare object nr.>
|
|
for example ``t_10#2`` -> lc.top.Below(<second obj>, 10)
|
|
|
|
3. <own attribute><compare operation><compare attribute>
|
|
[numerical argument]#<compare object nr.>
|
|
for example ``w%h50#2`` -> lc.width.PercentOf(<second obj>, wx.Height, 50) and ``t=b#1`` -> lc.top.SameAs(<first obj>, wx.Bottom)
|
|
|
|
Which one you need is defined by the <compare operation>
|
|
type. The following take type 1 (no object to compare with):
|
|
|
|
* '!': 'Absolute', '?': 'Unconstrained', '*': 'AsIs'
|
|
|
|
These take type 2 (need to be compared with another object)
|
|
|
|
* '<': 'LeftOf', '>': 'RightOf', '^': 'Above', '_': 'Below'
|
|
|
|
These take type 3 (need to be compared to another object
|
|
attribute)
|
|
|
|
* '=': 'SameAs', '%': 'PercentOf'
|
|
|
|
For all types, the <own attribute> letter can be any of
|
|
|
|
* 't': 'top', 'l': 'left', 'b': 'bottom',
|
|
* 'r': 'right', 'h': 'height', 'w': 'width',
|
|
* 'x': 'centreX', 'y': 'centreY'
|
|
|
|
If the operation takes an (optional) numerical argument, place it
|
|
in [numerical argument]. For type 3 directives, the <compare
|
|
attribute> letter can be any of
|
|
|
|
* 't': 'wxTop', 'l': 'wxLeft', 'b': 'wx.Bottom'
|
|
* 'r': 'wxRight', 'h': 'wxHeight', 'w': 'wx.Width',
|
|
* 'x': 'wxCentreX', 'y': 'wx.CentreY'
|
|
|
|
Note that these are the same letters as used for <own attribute>,
|
|
so you'll only need to remember one set. Finally, the object
|
|
whose attribute is refered to, is specified by #<compare object
|
|
nr>, where <compare object nr> is the 1-based (stupid, I know,
|
|
but I've gotten used to it) index of the object in the
|
|
objects_tuple argument.
|
|
|
|
Bugs:
|
|
|
|
Not entirely happy about the logic in the order of arguments
|
|
after the <compare operation> character.
|
|
|
|
Not all wxLayoutConstraint methods are included in the
|
|
syntax. However, the type 3 directives are generally the most
|
|
used. Further excuse: wxWindows layout constraints are at the
|
|
time of this writing not documented.
