self.setIcon(QIcon('icons/color.png')) self.setSizeHint(QSize(80, 60)) # size上述代码的作用

这段代码是在 PyQt5 中创建一个窗口部件(QWidget)并设置其图标和大小的代码。具体作用如下:
- `self.setIcon(QIcon('icons/color.png'))`:设置窗口部件的图标为 'icons/color.png',即当前目录下的图片文件。
- `self.setSizeHint(QSize(80, 60))`:设置窗口部件的推荐大小为 (80, 60) 像素。在某些布局中,推荐大小会被用来确定窗口部件的大小。
总的来说,这段代码的作用是为窗口部件设置图标和推荐大小。

QToolButton *m_btnSelCams = new QToolButton(); m_btnSelCams->setObjectName("public_toolbtn_above_tree"); QIcon iconSelCam; iconSelCam.addFile(".//skin//images//button//filter_cam.png", QSize(16, 16), QIcon::Normal, QIcon::On); iconSelCam.addFile(".//skin//images//button//filter_cam_h.png", QSize(16, 16), QIcon::Active, QIcon::On); iconSelCam.addFile(".//skin//images//button//filter_cam_p.png", QSize(16, 16), QIcon::Selected, QIcon::On); m_btnSelCams->setIcon(iconSelCam); m_btnSelCams->setIconSize(QSize(16, 16)); 设置悬浮态图标无效是什么原因
可能是因为没有设置悬浮态的图标。可以尝试添加以下代码:
```
QIcon iconSelCamHover;
iconSelCamHover.addFile(".//skin//images//button//filter_cam_h.png", QSize(16, 16), QIcon::Normal, QIcon::On);
m_btnSelCams->setIcon(iconSelCam);
m_btnSelCams->setToolTip("Select Cameras");
m_btnSelCams->setAutoRaise(true);
m_btnSelCams->setToolButtonStyle(Qt::ToolButtonIconOnly);
m_btnSelCams->setStyleSheet("QToolButton:hover{border: none; background-color: #f0f0f0;}");
m_btnSelCams->setCursor(Qt::PointingHandCursor);
m_btnSelCams->setFixedSize(24, 24);
m_btnSelCams->setSizePolicy(QSizePolicy::Fixed, QSizePolicy::Fixed);
```
这里我们添加了一个`iconSelCamHover`来存储悬浮态的图标,然后设置了一些其他属性,例如工具提示、自动升起、按钮样式、样式表、鼠标光标、固定大小和大小策略。你需要根据你的需要进行调整。
按钮和标签相互遮挡,该如何修改下列代码:from PyQt5.QtWidgets import QApplication, QWidget, QLabel, QPushButton, QGridLayout from PyQt5.QtGui import QPixmap,QIcon,QPixmap from PyQt5.QtCore import QSize app = QApplication([]) window = QWidget() window.setWindowTitle('贩卖车') label = QLabel('请选择您要购买的饮料或食品:') button1 = QPushButton() button1.setIcon(QIcon(QPixmap('coke.png'))) button1.setIconSize(QSize(100, 100)) button2 = QPushButton() button2.setIcon(QIcon(QPixmap('water.png'))) button2.setIconSize(QSize(100, 100)) button3 = QPushButton() button3.setIcon(QIcon(QPixmap('chips.png'))) button3.setIconSize(QSize(100, 100)) button4 = QPushButton() button4.setIcon(QIcon(QPixmap('chocolate.png'))) button4.setIconSize(QSize(100, 100)) button5 = QPushButton() button5.setIcon(QIcon(QPixmap('coke.png'))) button5.setIconSize(QSize(100, 100)) button6 = QPushButton() button6.setIcon(QIcon(QPixmap('water.png'))) button6.setIconSize(QSize(100, 100)) button7 = QPushButton() button7.setIcon(QIcon(QPixmap('chips.png'))) button7.setIconSize(QSize(100, 100)) button8 = QPushButton() button8.setIcon(QIcon(QPixmap('chocolate.png'))) button8.setIconSize(QSize(100, 100)) button9 = QPushButton() button9.setIcon(QIcon(QPixmap('chocolate.png'))) button9.setIconSize(QSize(100, 100)) button10 = QPushButton() button10.setIcon(QIcon(QPixmap('chocolate.png'))) button10.setIconSize(QSize(100, 100)) count_label1 = QLabel('0') count_label2 = QLabel('0') count_label3 = QLabel('0') count_label4 = QLabel('0') count_label5 = QLabel('0') count_label6 = QLabel('0') count_label7 = QLabel('0') count_label8 = QLabel('0') count_label9 = QLabel('0') count_label10 = QLabel('0') layout = QGridLayout() layout.addWidget(label, 0, 0, 1, 5) layout.addWidget(count_label1, 1, 0) layout.addWidget(count_label2, 1, 1) layout.addWidget(count_label3, 1, 2) layout.addWidget(count_label4, 1, 3) layout.addWidget(count_label5, 1, 4) layout.addWidget(count_label6, 2, 0) layout.addWidget(count_label7, 2, 1) layout.addWidget(count_label8, 2, 2) layout.addWidget(count_label9, 2, 3) layout.addWidget(count_label10, 2, 4) layout.addWidget(button1, 1, 0) layout.addWidget(button2, 1, 1) layout.addWidget(button3, 1, 2) layout.addWidget(button4, 1, 3) layout.addWidget(button5, 1, 4) layout.addWidget(button6, 2, 0) layout.addWidget(button7, 2, 1) layout.addWidget(button8, 2, 2) layout.addWidget(button9, 2, 3) layout.addWidget(button10, 2, 4) layout.setColumnStretch(0, 1) layout.setColumnStretch(4,1)
您可以通过设置按钮和标签的层级关系来解决按钮和标签相互遮挡的问题。可以使用QWidget的raise()方法将按钮提升到最上层,或者使用QWidget的lower()方法将标签降低到最下层。
对于这段代码,您可以尝试将以下内容添加到每个按钮的设置图标和大小的代码之后,使用raise()方法将按钮提升到最上层:
```python
button1.raise_()
button2.raise_()
button3.raise_()
button4.raise_()
button5.raise_()
button6.raise_()
button7.raise_()
button8.raise_()
button9.raise_()
button10.raise_()
```
如果以上方法无效,您还可以尝试将标签的放置位置稍微调整一下,例如将layout.addWidget(label, 0, 0, 1, 5)改为layout.addWidget(label, 0, 0, 1, 4),让标签所占的列数比按钮少一列。
希望这些方法能够帮助您解决问题。
