PYQT4小白的第一个图形程序

如图


以前对图形编程挺感兴趣的，刚刚看了pyqt4的教程写了一个入门的小白程序。

接下来在写写这样方便以后操作脚本。

# -*-coding:utf-8 -*-
import sys
from PyQt4 import QtCore, QtGui, uic

qtCreatorFile = "graph.ui" # Enter file here.

Ui_MainWindow, QtBaseClass = uic.loadUiType(qtCreatorFile)

class MyApp(QtGui.QMainWindow, Ui_MainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
Ui_MainWindow.__init__(self)
self.setupUi(self)
self.heart.clicked.connect(self.heart1)
self.triangle.clicked.connect(self.triangle1)
self.square.clicked.connect(self.square1)
self.rectangle.clicked.connect(self.rectangle1)

def heart1(self):

a = '\n'.join([''.join([('PYTHON!'[(x-y)%7]if((x*0.05)**2+(y*0.1)**2-1)**3-(x*0.05)**2*(y*0.1)**3<=0 else' ')for x in range(-30,30)])for y in range(15,-15,-1)])
self.result.setText(a)

def triangle1(self):

d = 10
l=[' '*(2*d-1)]*d #初始化列表
for i in range(d):
l[i]=list(l[i]) #字符串转列表
x=i
y=0
x=d-x-1 #确定每行首项
l[i][x]="*"
while y<i:
x+=2 #公差为2
l[i][x]='*'
y+=1
l[i]=''.join(l[i]) #列表转字符串
print(l[i]) #打印每行
self.result.setText(l[i])
def square1(self):
for k in range(0,100):
for i in range(0,100):
print "*",
i += 1
k += 1
print "\n"
self.result.setText()
def rectangle1(self):
for k in range(0,100):
for i in range(0,200):
print "*",
i += 1
k += 1
print "\n"
self.result.setText()
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
window = MyApp()
window.show()
sys.exit(app.exec_())
