我对python很陌生,我正在尝试用PyQt5重写一个GUI。我制作的GUI是用Tkinter编写的。我正在使用框架来显示不同的页面。使用Tkinter,我成功地使用tkraise()函数将页面放到了最前面。但是使用PyQt5,函数似乎被忽略了。
该文件是一个测试文件,在将它添加到我的主文件之前,我尝试了不同的东西。在Dothing函数中,我添加了print("yes")函数,以查看它是否进入该函数,但它没有以某种方式使用raise_()函数。
有谁能解释我做错了什么,或者给我发送一个链接,以获取更多的信息,所以我自己搜索。我已经看了QT和其他论坛的网站,但我找不到答案。
我的档案是这样的:
import sys
from PyQt5.QtWidgets import (QWidget, QGridLayout, QPushButton, QApplication, QFrame, QLabel, QColorDialog)
from PyQt5.QtGui import (QColor)
Lijst = ["Ferri", "Yvonne", "Ineke"] # , "Sidneger", "Deniel", "Tobie", "Nicol"
class Test(QWidget):
def __init__(self, *args, **kwargs):
super().__init__()
self.List = [(255,0,0), (0,255,0), (0,0,255)]
# self.List = Lijst
# container = QFrame(self)
self.setGeometry(300,300,300,300)
self.Frames = {}
for F in (self.List):
selected_color = QColor(F[0],F[1],F[2])
self.frame = QFrame(self)
self.frame.setStyleSheet("QWidget { background-color: %s}" % selected_color.name())
self.frame.setGeometry(100, 0, 300, 300)
Framas = Pages(self.frame, self, selected_color)
self.Frames[F] = Framas
def DoThing(self):
self.Frames[(255, 0, 0)].raise_()
print("yes")
pass
def DoThing2(self):
self.Frames[(0, 255, 0)].raise_()
pass

self.Frames[(0, 0, 255)].raise_()
pass

def __init__(self, parent, controller, selected_color, *args, **kwargs):
super().__init__()
self.controller = controller
self.frame = parent
self.button = QPushButton("Change", self.frame) # adding frame as parent
self.button.move(10, 10)
self.button.clicked.connect(self.controller.DoThing)

拥有原始代码的源代码很难准确地知道您需要什么。所以我会尽力帮你。
首先,您必须只使用一个QFrame,每次迭代都要创建两个:设置颜色的QFrame,而另一个是页面。
其次,您在页面上使用raise_(),因为您将页面添加到字典中,但是页面没有颜色,而是另一个QFrame。
