[英]python pyqt5 add file name to getSaveFileName
I'm trying to add a default name to QFileDialog()
the images below illustrate.我正在尝试向QFileDialog()
添加默认名称,如下图所示。
This is what I get (no filename)这就是我得到的(没有文件名)
and this is what I want to achieve without having to input it manually, I want to pass the file_name
threw a function and have that name show up there.这就是我想要实现的,而无需手动输入它,我想通过file_name
抛出一个函数并在那里显示该名称。
This is the code im trying to make to work:这是我试图使其工作的代码:
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5 import *
import sys
class mainwindowUI(QMainWindow):
def __init__(self):
super(mainwindowUI, self).__init__()
self.exportFiles('test.mp3')
def exportFiles(self,file_name):
filename, _ = QFileDialog.getSaveFileName(self, "Save audio file", "", "Audio Files (*.mp3)")
if filename:
print(filename)
if __name__ == '__main__':
app = QApplication(sys.argv)
window = mainwindowUI()
app.exec_()
I tried to add options:我尝试添加选项:
filename, _ = QFileDialog.getSaveFileName(self, "Save audio file", "", "Audio Files (*.mp3)", options=QFileDialog.setLabelText(file_name))
But this is incorrect and i have no idea how to make it work...但这是不正确的,我不知道如何使它工作......
Anyone know how to add a file name to save file dialog?任何人都知道如何添加文件名以保存文件对话框?
The third argument indicates the initial name:第三个参数表示初始名称:
def exportFiles(self, file_name):
default_dir ="/home/qt_user/Documents"
default_filename = os.path.join(default_dir, file_name)
filename, _ = QFileDialog.getSaveFileName(
self, "Save audio file", default_filename, "Audio Files (*.mp3)"
)
if filename:
print(filename)
First create a save-as action首先创建一个另存为动作
self.saveas=QAction(QtGui.QIcon('saveas.png'),'save-as')
Add the save-as action to toolbar将另存为操作添加到工具栏
toolbar=self.addToolbar('toolbar');
toolbar.addAction(self.saveas);
Sub this for your QFileDialog code将此用于您的 QFileDialog 代码
Fn, _=QFileDialog.getSaveFileName(self,'export pdf',file_name,'Pdf files(.pdf);;All files()');
when connecting the signal to the slot do this将信号连接到插槽时,请执行此操作
Self.Saveas.toggled.connect(self.exportfiles('name of default file');
