🦑 Get in on GitLab Sprinkle some winter mood into Your PySide GUIs with this widget: When creating VFX pipeline tools, whose main purpose it is to take the annoying part out of all the repetitive and tedious work, it’s nice to add some small “easter eggs”. If you write pipeline tools (or other Qt for Python / PySide based tools) feel free to use this little widget to decorate your GUI with some totally unnecessary but fun snowflakes. ...
I recently started exploring p5js to up my math game a little and practice per-pixel manipulation. I picked p5js because I like the interactivity and real-time feedback, it has an easy syntax and it’s easy to test the code in either the web-editor or with the processing app (using the p5js plugin). After some fiddling around the “finished product” can distort any image using noise and the mouse position: Transform with MousePos ...
I made a stupid thing. But it was fun and I learned some stuff about QPropertyAnimations along the way. Here’s the code import sys from random import randint try: from PySide import QtCore, QtGui, QtGui as QtWidgets except: from PySide2 import QtCore, QtGui, QtWidgets class DodgeButton(QtWidgets.QPushButton): def __init__(self, parent=None): super(DodgeButton, self).__init__(parent=parent) # PROPERTIES self.origSize = [self.size().width(), self.size().height()] self.aniSpeed = 120 self.aniPosition = QtCore.QPropertyAnimation(self, b"pos") self.aniPosition.setDuration(self.aniSpeed) self.aniScale = QtCore.QPropertyAnimation(self, b"size") self.aniScale.setDuration(self.aniSpeed) # EVENTS self.clicked.connect(self.win) # INIT xPos = parent.width()/2-self.width()/2 yPos = parent.height()/2-self.height()/2 self.move(xPos, yPos) def win(self): print("ALRIGHTY!") def enterEvent(self, event): self.randomScale() self.randomMove() def randomMove(self): """ move to a random position """ randX = randint(0+self.width(), self.parent().width()-self.width()) randY = randint(0+self.height(), self.parent().height()-self.height()) # Move self.aniPosition.setStartValue(self.pos()) self.aniPosition.setEndValue(QtCore.QPoint(randX, randY)) self.aniPosition.start() def randomScale(self): """ scale to random size """ randMult = float(randint(50,200))/100.0 # Scale self.aniScale.setStartValue(self.size()) newSize = scalePropo([self.origSize[0], self.origSize[1]], self.origSize[0]*randMult) sizeX = newSize[0] sizeY = newSize[1] self.aniScale.setEndValue(QtCore.QSize(sizeX, sizeY)) self.aniScale.start() class MainWindow(QtWidgets.QDialog): def __init__(self, buttonName="Analyze", parent=None): super(MainWindow, self).__init__(parent) layout = QtWidgets.QVBoxLayout() self.setLayout(layout) self.setFixedSize(500, 500) # INIT self.button = DodgeButton(self) self.button.setText(buttonName) def scalePropo(oldSize=None,newWidth=None): ''' Scales an input size proportionally to the new desired width. :param oldsize : : The current size [x,y] :param newsize : : The new desired width ''' oldWidth = float(oldSize[0]) oldHeight = float(oldSize[1]) newHeight = (oldHeight/oldWidth)*float(newWidth) newSize = [newWidth,newHeight] return newSize def setup(): app = QtWidgets.QApplication(sys.argv) win1 = MainWindow("Analyze") win2 = MainWindow("Are you sure?") win3 = MainWindow("Are you really sure?") win1.button.clicked.connect(win2.exec_) win2.button.clicked.connect(win3.exec_) win1.exec_() # app.exec_() sys.exit(0) if __name__ == '__main__': setup()
