PyQT中讓QMessageBox按鈕顯示中文
阿新 • • 發佈：2019-01-04
QMessageBox.warning(self,'錯誤', '使用者名稱和密碼不匹配', QMessageBox.Yes, QMessageBox.Yes)
以上一條語句輸出，但更改前這樣顯示的，中英文混合，看著彆扭。
參考了http://srinikom.github.io/pyside-docs/PySide/QtGui/QMessageBox.html上的文件
self.box = QMessageBox(QMessageBox.Warning, "錯誤", "使用者名稱和密碼不匹配！")
self.box.addButton(self.tr("確定"), QMessageBox.YesRole)
#self.box.addButton(self.tr("取消"), QMessageBox.NoRole)
self.box.show() self.box = QMessageBox(QMessageBox.Warning, "錯誤", "使用者名稱和密碼不匹配！") qyes=self.box.addButton(self.tr("確定"), QMessageBox.YesRole) qno=self.box.addButton(self.tr("取消"), QMessageBox.NoRole) self.box.exec_() if self.box.clickedButton() == qyes: print('okokok') else: return
其中，引數QMessageBox.YesRole可以為以下幾種：
| QMessageBox.InvalidRole | The button is invalid. |
| QMessageBox.AcceptRole | Clicking the button causes the dialog to be accepted (e.g. OK). |
| QMessageBox.RejectRole | Clicking the button causes the dialog to be rejected (e.g. Cancel). |
| QMessageBox.DestructiveRole | Clicking the button causes a destructive change (e.g. for Discarding Changes) and closes the dialog. |
| QMessageBox.ActionRole | Clicking the button causes changes to the elements within the dialog. |
| QMessageBox.HelpRole | The button can be clicked to request help. |
| QMessageBox.YesRole | The button is a “Yes”-like button. |
| QMessageBox.NoRole | The button is a “No”-like button. |
| QMessageBox.ApplyRole | The button applies current changes. |
| QMessageBox.ResetRole | The button resets the dialog’s fields to default values. |
