python-标签中的小部件放置
作者：互联网
所以我有这段代码：
from PyQt5.QtWidgets import QMainWindow, QApplication, QPushButton, QWidget, QAction, QTabWidget, QVBoxLayout, QHBoxLayout, QComboBox, QLabel
from PyQt5.QtGui import QIcon
from PyQt5.QtCore import pyqtSlot
from lang import getLang
import sys, os, configparser
config = configparser.ConfigParser()
config.read("Settings.ini")
# Config get setting and change setting
#print(config.get("Main", "language"))
#config.set("Main", "language", "danish")
#with open("Settings.ini", "w") as cfg_file:
#config.write(cfg_file)
class App(QMainWindow):
def __init__(self):
super().__init__()
# Window Settings
self.x, self.y, self.w, self.h = 0, 0, 300, 200
self.setGeometry(self.x, self.y, self.w, self.h)
self.window = MainWindow(self)
self.setCentralWidget(self.window)
self.setWindowTitle("Window title") # Window Title
self.show()
class MainWindow(QWidget):
def __init__(self, parent):
super(QWidget, self).__init__(parent)
layout = QVBoxLayout(self)
# Run this after settings
self.lang = getLang(config.get("Main", "language"))
# Initialize tabs
tab_holder = QTabWidget() # Create tab holder
tab_1 = QWidget() # Tab one
tab_2 = QWidget() # Tab two
# Add tabs
tab_holder.addTab(tab_1, self.lang["tab_1_title"]) # Add "tab1" to the tabs holder "tabs"
tab_holder.addTab(tab_2, self.lang["tab_2_title"]) # Add "tab2" to the tabs holder "tabs"
# Create first tab
tab_1.layout = QVBoxLayout(self)
tab_2.layout = QVBoxLayout(self)
# Buttons
button_start = QPushButton(self.lang["btn_start"])
button_stop = QPushButton(self.lang["btn_stop"])
button_test = QPushButton(self.lang["btn_test"])
# Button Extra
button_start.setToolTip("This is a tooltip for the button!") # Message to show when mouse hover
button_start.clicked.connect(self.on_click)
button_stop.clicked.connect(self.on_click)
button_test.clicked.connect(self.on_click)
#button_start.setEnabled(False)
# comboBox
label_language = QLabel("Language")
combo_language = QComboBox(self)
combo_language.addItem(self.lang["language_danish"])
combo_language.addItem(self.lang["language_english"])
# Move widgets
combo_language.move(50, 150)
label_language.move(50, 50)
# Tab Binding
self.AddToTab(tab_1, button_start)
self.AddToTab(tab_1, button_stop)
self.AddToTab(tab_2, label_language)
self.AddToTab(tab_2, combo_language)
# Add tabs to widget
tab_1.setLayout(tab_1.layout)
tab_2.setLayout(tab_2.layout)
layout.addWidget(tab_holder)
self.setLayout(layout)
@pyqtSlot()
def on_click(self):
button = self.sender().text()
if button == self.lang["btn_start"]:
print("Dank")
elif button == self.lang["btn_stop"]:
print("Not dank")
def AddToTab(self, tab, obj):
tab.layout.addWidget(obj)
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = App()
sys.exit(app.exec_())
当前,它在一个选项卡上创建一个包含2个按钮的窗口.一个“开始”和“停止”按钮,除了打印文本外,没有其他实际功能.
在选项卡2上,我有一个标签为“ Language：”(语言：)和一个包含“丹麦语”和“英语”的下拉菜单.
我的问题是,它的放置位置确实很奇怪和令人讨厌,如下所示：
我不确定如何更改位置,因为我不能仅在文本标签,按钮和下拉菜单上使用.move,因为它们位于选项卡中.
例如,在第二个标签上,我希望标签“ Language：”位于下拉菜单的左侧.
解决方法:
引起此问题的原因是您使用QVBoxLayout设置每个选项卡内的小部件.布局的任务是管理小部件的位置和大小,因此除了没有必要之外,您不能使用move().
解决方案是为每个选项卡创建一个自定义布局,但是保持顺序将为每个选项卡创建一个自定义小部件,在第一个选项卡的情况下,我将继续使用QVBoxlayout,但要添加拉伸以使小部件保持在最高位置.在第二种情况下,我将结合使用QVBoxLayout和QHBoxLayout,QHBoxLayout将使用它来放置QLabel和QComboBox,而QVBoxLayout将使用它来将小部件推到顶部.
实现以上内容,出于明显的原因,我省略了lang,我们得到了以下内容：
