ColorWell

class vanilla.ColorWell(posSize, callback=None, color=None)

A control that allows for showing and choosing a color value.

ColorWell objects handle NSColor objects.:

from AppKit import NSColor
from vanilla import *

class ColorWellDemo(object):

    def __init__(self):
        self.w = Window((100, 50))
        self.w.colorWell = ColorWell((10, 10, -10, -10),
                            callback=self.colorWellEdit,
                            color=NSColor.redColor())
        self.w.open()

    def colorWellEdit(self, sender):
        print("color well edit!", sender.get())

ColorWellDemo()

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

callback The method to be caled when the user selects a new color.

color A NSColor object. If None is given, the color shown will be white.

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.

enable(onOff)

Enable or disable the object. onOff should be a boolean.

get()

Get the NSColor object representing the current color in the color well.

getNSColorWell()

Return the NSColorWell that this object wraps.

getPosSize()

The position and size of the object as a tuple of form (left, top, width, height).

isVisible()

Return a bool indicating if the object is visible or not.

move(x, y)

Move the object by x units and y units.

resize(width, height)

Change the size of the object to width and height.

set(color)

Set the color in the color well.

color A NSColor object representing the color to be displayed in the color well.

setPosSize(posSize, animate=False)

Set the position and size of the object.

posSize A tuple of form (left, top, width, height).

animate A boolean flag telling to animate the transition. Off by default.

show(onOff)

Show or hide the object.
