ColorWell
(posSize, callback=None, color=None, colorWellStyle=None)¶ A control that allows for showing and choosing a color value.
ColorWell objects handle NSColor objects.
from AppKit import NSColor from vanilla import Window, ColorWell class ColorWellDemo: 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.
colorWellStyle A string representing the desired color well style. The options are:
“default” “minimal” “expanded” -
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:
- strings that follow the Visual Format Language
- dictionaries with the following key/value pairs:
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.
