Pyside6 QFileDialog
常用函数
函数作用getOpenFileName打开单个已存在的文件getOpenFileNames打开多个已存在的文件getSaveFileName打开需要保存的文件getExistingDirectory打开已存在的文件夹
getOpenFileName
getOpenFileName是打开一个已经存在的文件如果文件存在就返回该文件的文件路径如果不存在就返回空。
static PySide6.QtWidgets.QFileDialog.getOpenFileName([parentNone[, caption[, dir[, filter[, selectedFilter[, optionsQFileDialog.Options()]]]]]])# parent:父组件
# caption:对话框的标题
# dir:默认路径 比如在windows下默认选择C盘则应该为 C:\\
# filter:话框的后缀名过滤器 比如筛选txt和bin文件 图像文件 file(*.txt *.bin) ;;image(*.jpg *.bmp *.png *.gif)
# selectedFilter:默认选择的过滤器
# options:参数options参数可选ShowDirsOnly : QFileDialog.Option ... # 0x1DontResolveSymlinks : QFileDialog.Option ... # 0x2DontConfirmOverwrite : QFileDialog.Option ... # 0x4DontUseNativeDialog : QFileDialog.Option ... # 0x8ReadOnly : QFileDialog.Option ... # 0x10HideNameFilterDetails : QFileDialog.Option ... # 0x20DontUseCustomDirectoryIcons: QFileDialog.Option ... # 0x40可用|运算符进行组合file QFileDialog.getOpenFileName(parent None, caption 请选择选择文件, dir ,filter file(*.txt *.bin) ;;image(*.jpg *.bmp *.png *.gif)) # 选择后缀为.txt .bin的文件 和.jpg .bmp .png .gif的图像文件getOpenFileNames
getOpenFileNames是打开多个已经存在的文件如果文件存在就返回该文件的文件路径如果不存在就返回空。
static PySide6.QtWidgets.QFileDialog.getOpenFileNames([parentNone[, caption[, dir[, filter[, selectedFilter[, optionsQFileDialog.Options()]]]]]])# parent:父组件
# caption:对话框的标题
# dir:默认路径 比如在windows下默认选择C盘则应该为 C:\\
# 话框的后缀名过滤器 比如筛选txt和bin文件 图像文件 file(*.txt *.bin) ;;image(*.jpg *.bmp *.png *.gif)
# selectedFilter:默认选择的过滤器
# options:参数options参数可选ShowDirsOnly : QFileDialog.Option ... # 0x1DontResolveSymlinks : QFileDialog.Option ... # 0x2DontConfirmOverwrite : QFileDialog.Option ... # 0x4DontUseNativeDialog : QFileDialog.Option ... # 0x8ReadOnly : QFileDialog.Option ... # 0x10HideNameFilterDetails : QFileDialog.Option ... # 0x20DontUseCustomDirectoryIcons: QFileDialog.Option ... # 0x40可用|运算符进行组合file QFileDialog.getOpenFileNames(parent None, caption 请选择选择文件, dir ,filter file(*.txt *.bin) ;;image(*.jpg *.bmp *.png *.gif)) # 选择后缀为.txt .bin的文件 和.jpg .bmp .png .gif的图像文件getExistingDirectory
getExistingDirectory是打开单个已存在的文件夹如果文件夹存在就返回该文件夹的的路径如果不存在就返回空。
static PySide6.QtWidgets.QFileDialog.getExistingDirectory([parentNone[, caption[, dir[, optionsQFileDialog.Option.ShowDirsOnly]]]])# parent:父组件
# caption:对话框的标题
# dir:默认路径 比如在windows下默认选择C盘则应该为 C:\\
# options:参数options参数可选ShowDirsOnly : QFileDialog.Option ... # 0x1DontResolveSymlinks : QFileDialog.Option ... # 0x2DontConfirmOverwrite : QFileDialog.Option ... # 0x4DontUseNativeDialog : QFileDialog.Option ... # 0x8ReadOnly : QFileDialog.Option ... # 0x10HideNameFilterDetails : QFileDialog.Option ... # 0x20DontUseCustomDirectoryIcons: QFileDialog.Option ... # 0x40可用|运算符进行组合file QFileDialog.getExistingDirectory(self, 选择文件夹,,QFileDialog.ShowDirsOnly| QFileDialog.DontResolveSymlinks)getSaveFileName
getSaveFileName是获取需要保存文件的文件名此函数不会帮你创建文件该函数允许返回不存在的文件路径调用成功后该函数会返回文件的路径如果取消则返回空。
static PySide6.QtWidgets.QFileDialog.getSaveFileName([parentNone[, caption[, dir[, filter[, selectedFilter[, optionsQFileDialog.Options()]]]]]])# parent:父组件
# caption:对话框的标题
# dir:默认路径 比如在windows下默认选择C盘则应该为 C:\\
