ProgressBar
- class vanilla.ProgressBar(posSize, minValue=0, maxValue=100, isIndeterminate=False, sizeStyle='regular', progressStyle='bar')
A standard progress bar.
from vanilla import Window, ProgressBar, Button class ProgressBarDemo: def __init__(self): self.w = Window((200, 65)) self.w.bar = ProgressBar((10, 10, -10, 16)) self.w.button = Button((10, 35, -10, 20), "Go!", callback=self.showProgress) self.w.open() def showProgress(self, sender): import time self.w.bar.set(0) for i in range(10): self.w.bar.increment(10) time.sleep(.2) ProgressBarDemo()
posSize Tuple of form (left, top, width, height) or “auto” representing the position and size of the progress bar. The height of the progress bar should match the appropriate value for the given sizeStyle.
Standard Dimensions
Regular
H
16
Small
H
10
minValue The minimum value of the progress bar.
maxValue The maximum value of the progress bar.
isIndeterminate Boolean representing if the progress bar is indeterminate. Determinate progress bars show how much of the task has been completed. Indeterminate progress bars simply show that the application is busy.
sizeStyle A string representing the desired size style of the pregress bar. The options are:
“regular”
“small”
- 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.
