Group

class vanilla.Group(posSize, blendingMode=None)

An invisible container for controls.

To add a control to a group, simply set it as an attribute of the group.:

from vanilla import *

class GroupDemo(object):

    def __init__(self):
        self.w = Window((150, 50))
        self.w.group = Group((10, 10, -10, -10))
        self.w.group.text = TextBox((0, 0, -0, -0),
                                "This is a group")
        self.w.open()

GroupDemo()

No special naming is required for the attributes. However, each attribute must have a unique name.

posSize Tuple of form (left, top, width, height) or “auto” representing the position and size of the group.

blendingMode The blending mode for the window. These are the possible options:

None No special blending.
“behindWindow” Blend with the content behind the window.
“withinWindow” Blend with the content within the window.
addAutoPosSizeRules(rules, metrics=None)

Add auto layout rules for controls/view in this view.

rules must be a list of rule definitions. Rule definitions may take two forms:

key value
“view1” The vanilla wrapped view for the left side of the rule.
“attribute1” The attribute of the view for the left side of the rule. See below for options.
“relation” (optional) The relationship between the left side of the rule and the right side of the rule. See below for options. The default value is “==”.
“view2” The vanilla wrapped view for the right side of the rule.
“attribute2” The attribute of the view for the right side of the rule. See below for options.
“multiplier” (optional) The constant multiplied with the attribute on the right side of the rule as part of getting the modified attribute. The default value is 1.
“constant” (optional) The constant added to the multiplied attribute value on the right side of the rule to yield the final modified attribute. The default value is 0.

The attribute1 and attribute2 options are:

value AppKit equivalent
“left” NSLayoutAttributeLeft
“right” NSLayoutAttributeRight
“top” NSLayoutAttributeTop
“bottom” NSLayoutAttributeBottom
“leading” NSLayoutAttributeLeading
“trailing” NSLayoutAttributeTrailing
“width” NSLayoutAttributeWidth
“height” NSLayoutAttributeHeight
“centerX” NSLayoutAttributeCenterX
“centerY” NSLayoutAttributeCenterY
“baseline” NSLayoutAttributeBaseline
“lastBaseline” NSLayoutAttributeLastBaseline
“firstBaseline” NSLayoutAttributeFirstBaseline

Refer to the NSLayoutAttribute documentation for the information about what each of these do.

The relation options are:

value AppKit equivalent
“<=” NSLayoutRelationLessThanOrEqual
“==” NSLayoutRelationEqual
“>=” NSLayoutRelationGreaterThanOrEqual

Refer to the NSLayoutRelation documentation for the information about what each of these do.

metrics may be either None or a dict containing key value pairs representing metrics keywords used in the rules defined with strings.
