一、简介

QInputDialog类提供了一个简单的便捷对话框，可以从用户那里获取用户录入的单个值，它提供了4种数据类型的输入；每个输入都包含一个提示标签，一个输入控件；还包括一个确定输入(Ok)按钮和一个取消输入(Cancel)按钮。

字符串型（方法=QInputDialog.getText）---- QLineEdit

Int类型数据（方法=QInputDialog.getInt）---- QSpinBox

double类型数据（方法=QInputDialog.getDouble）----

下拉列表框的条目（方法=QInputDialog.getItem）---- QComboBox

二、部分代码

2.1 字符串

def getText(self):text, okPressed = QInputDialog.getText(self, "Get text","Your name:", QLineEdit.Normal, "")if okPressed and text != '':print(text)

2.2 int

def getInteger(self):i, okPressed = QInputDialog.getInt(self, "Get integer","Percentage:", 28, 0, 100, 1)if okPressed:print(i)

2.3 double

def getDouble(self):d, okPressed = QInputDialog.getDouble(self, "Get double","Value:", 10.05, 0, 100, 10)if okPressed:print(d)

2.4 条目

def getDouble(self):d, okPressed = QInputDialog.getDouble(self, "Get double","Value:", 10.05, 0, 100, 10)if okPressed:print(d)
