Python: pyqt5 自己写一个窗口文本编辑器
|
PyQt5是Digia的一套Qt5应用框架与python的结合，同时支持2.x和3.x。Qt库由Riverbank Computing开发，是最强大的GUI库之一。 >>> 今天，我们将尝试用pyqt5写一个文本编辑器。效果如图：
支持以下功能：复制、剪切、粘帖、保存、全选、读取、撤回、前进、加粗、斜体、下划线、字体、字号、左中右对齐、打印。 >>> Tips：完整代码在本页最后~ 一、安装模块使用pip安装pyqt5： pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pyqt5 二、导入模块导入所需模块： from PyQt5.QtGui import * from PyQt5.QtWidgets import * from PyQt5.QtCore import * from PyQt5.QtPrintSupport import * import os import sys import uuid 三、初始化定义首先，我们先初始化定义一些后文所需函数。这里如果有看不懂，看到后文就可以理解了。 FONT_SIZES = [7, 8, 9, 10, 11, 12, 13, 14, 18, 24, 36, 48, 64, 72, 96, 144, 288] IMAGE_EXTENSIONS = ['.jpg','.png','.bmp'] HTML_EXTENSIONS = ['.htm', '.html'] def hexuuid(): return uuid.uuid4().hex def splitext(p): return os.path.splitext(p)[1].lower() class TextEdit(QTextEdit): def canInsertFromMimeData(self, source): if source.hasImage(): return True else: return super(TextEdit, self).canInsertFromMimeData(source) def insertFromMimeData(self, source): cursor = self.textCursor() document = self.document() if source.hasUrls(): for u in source.urls(): file_ext = splitext(str(u.toLocalFile())) if u.isLocalFile() and file_ext in IMAGE_EXTENSIONS: image = QImage(u.toLocalFile()) document.addResource(QTextDocument.ImageResource, u, image) cursor.insertImage(u.toLocalFile()) else: break else: return elif source.hasImage(): image = source.imageData() uuid = hexuuid() document.addResource(QTextDocument.ImageResource, uuid, image) cursor.insertImage(uuid) return super(TextEdit, self).insertFromMimeData(source) 四、设置主窗口开始使用pyqt5，建立一个主窗口，添加按钮等元素位置。 class MainWindow(QMainWindow): def __init__(self, *args, **kwargs): super(MainWindow, self).__init__(*args, **kwargs) layout = QVBoxLayout() self.editor = TextEdit() self.editor.setAutoFormatting(QTextEdit.AutoAll) self.editor.selectionChanged.connect(self.update_format) font = QFont('Times', 12) self.editor.setFont(font) self.editor.setFontPointSize(12) self.path = None layout.addWidget(self.editor) container = QWidget() container.setLayout(layout) self.setCentralWidget(container) self.status = QStatusBar()

print_action.triggered.connect(self.file_print) file_menu.addAction(print_action) file_toolbar.addAction(print_action) edit_toolbar = QToolBar("编辑") edit_toolbar.setIconSize(QSize(16, 16)) self.addToolBar(edit_toolbar) edit_menu = self.menuBar().addMenu("&编辑") undo_action = QAction(QIcon(os.path.join('images', 'arrow-curve-180-left.png')), "撤回", self)

QAction(QIcon(os.path.join('images', 'clipboard-paste-document-text.png')), "粘帖", self) paste_action.setStatusTip("从剪贴板粘帖..") cut_action.setShortcut(QKeySequence.Paste) paste_action.triggered.connect(self.editor.paste) edit_toolbar.addAction(paste_action) edit_menu.addAction(paste_action) select_action = QAction(QIcon(os.path.join('images', 'selection-input.png')), "全选", self) select_action.setStatusTip("全选所有文字..") cut_action.setShortcut(QKeySequence.SelectAll) select_action.triggered.connect(self.editor.selectAll) edit_menu.addAction(select_action) edit_menu.addSeparator() wrap_action = QAction(QIcon(os.path.join('images', 'arrow-continue.png')), "自动换行", self) wrap_action.setStatusTip("当文字长度超过边框大小时自动换行..") wrap_action.setCheckable(True) wrap_action.setChecked(True) wrap_action.triggered.connect(self.edit_toggle_wrap) edit_menu.addAction(wrap_action) format_toolbar = QToolBar("格式") format_toolbar.setIconSize(QSize(16, 16)) self.addToolBar(format_toolbar) format_menu = self.menuBar().addMenu("&格式") self.fonts = QFontComboBox() self.fonts.currentFontChanged.connect(self.editor.setCurrentFont) format_toolbar.addWidget(self.fonts) self.fontsize = QComboBox() self.fontsize.addItems([str(s) for s in FONT_SIZES]) self.fontsize.currentIndexChanged[str].connect(lambda s: self.editor.setFontPointSize(float(s)) ) format_toolbar.addWidget(self.fontsize) self.bold_action = QAction(QIcon(os.path.join('images', 'edit-bold.png')), "加粗", self) self.bold_action.setStatusTip("加粗选定内容..") self.bold_action.setShortcut(QKeySequence.Bold) self.bold_action.setCheckable(True) self.bold_action.toggled.connect(lambda x: self.editor.setFontWeight(QFont.Bold if x else QFont.Normal)) format_toolbar.addAction(self.bold_action) format_menu.addAction(self.bold_action) self.italic_action = QAction(QIcon(os.path.join('images', 'edit-italic.png')), "斜体", self) self.italic_action.setStatusTip("将选定内容设为斜体..") self.italic_action.setShortcut(QKeySequence.Italic) self.italic_action.setCheckable(True) self.italic_action.toggled.connect(self.editor.setFontItalic) format_toolbar.addAction(self.italic_action) format_menu.addAction(self.italic_action) self.underline_action = QAction(QIcon(os.path.join('images', 'edit-underline.png')), "下划线", self) self.underline_action.setStatusTip("将选定内容加下划线..") self.underline_action.setShortcut(QKeySequence.Underline) self.underline_action.setCheckable(True) self.underline_action.toggled.connect(self.editor.setFontUnderline) format_toolbar.addAction(self.underline_action) format_menu.addAction(self.underline_action) format_menu.addSeparator() self.alignl_action = QAction(QIcon(os.path.join('images', 'edit-alignment.png')), "靠左对齐", self) self.alignl_action.setStatusTip("将文本靠左对齐..") self.alignl_action.setCheckable(True) self.alignl_action.triggered.connect(lambda: self.editor.setAlignment(Qt.AlignLeft)) format_toolbar.addAction(self.alignl_action) format_menu.addAction(self.alignl_action) self.alignc_action = QAction(QIcon(os.path.join('images',

format_group.addAction(self.alignl_action) format_group.addAction(self.alignc_action) format_group.addAction(self.alignr_action) format_group.addAction(self.alignj_action) format_menu.addSeparator() self._format_actions = [ self.fonts, self.fontsize, self.bold_action, self.italic_action, self.underline_action] self.update_format() self.update_title() self.show() 五、定义功能也是在window的class里，我们定义保存等等的功能 def block_signals(self, objects, b): for o in objects: o.blockSignals(b) def update_format(self): self.block_signals(self._format_actions, True) self.fonts.setCurrentFont(self.editor.currentFont()) self.fontsize.setCurrentText(str(int(self.editor.fontPointSize()))) self.italic_action.setChecked(self.editor.fontItalic()) self.underline_action.setChecked(self.editor.fontUnderline()) self.bold_action.setChecked(self.editor.fontWeight() == QFont.Bold) self.alignl_action.setChecked(self.editor.alignment() == Qt.AlignLeft) self.alignc_action.setChecked(self.editor.alignment() == Qt.AlignCenter) self.alignr_action.setChecked(self.editor.alignment() == Qt.AlignRight) self.alignj_action.setChecked(self.editor.alignment() == Qt.AlignJustify) self.block_signals(self._format_actions, False) def dialog_critical(self, s): dlg = QMessageBox(self) dlg.setText(s) dlg.setIcon(QMessageBox.Critical) dlg.show() def file_open(self): path, _ = QFileDialog.getOpenFileName(self, "Open file", "", "HTML documents (*.html);Text documents (*.txt);All files (*.*)") try: with open(path, 'rU') as f: text = f.read() except Exception as e: self.dialog_critical(str(e)) else: self.path = path self.editor.setText(text) self.update_title() def file_save(self): if self.path is None: return self.file_saveas() text = self.editor.toHtml() if splitext(self.path) in HTML_EXTENSIONS else self.editor.toPlainText() try: with open(self.path, 'w') as f: f.write(text) except Exception as e: self.dialog_critical(str(e)) def file_saveas(self): path, _ = QFileDialog.getSaveFileName(self, "Save file", "", "HTML documents (*.html);Text documents (*.txt);All files (*.*)") if not path: return text = self.editor.toHtml() if splitext(path) in HTML_EXTENSIONS else self.editor.toPlainText() try: with open(path, 'w') as f: f.write(text) except Exception as e: self.dialog_critical(str(e)) else: self.path = path self.update_title() def file_print(self): dlg = QPrintDialog() if dlg.exec_(): self.editor.print_(dlg.printer()) def update_title(self): self.setWindowTitle("%s - 轩氏记事本 XuanNotepad" % (os.path.basename(self.path) if self.path else "Untitled")) def edit_toggle_wrap(self): self.editor.setLineWrapMode( 1 if self.editor.lineWrapMode() == 0 else 0 ) 六、生成窗口最后一步，生成窗口（这里的applicationname你可以改掉）： if __name__ == '__main__': app = QApplication(sys.argv) app.setApplicationName("轩氏记事本 XuanNotepad") window = MainWindow() window.resize(1300,750) app.exec_() 七、最终效果运行程序，我们来看一下效果如何！
