import xlwings as xw
from flexx import flx
class FileViewer(flx.FileBrowserWidget):
    @flx.reaction("selected")
    def fileSelected(self, *events):
        ev = events[-1]
        print(ev)

class NewLabel(flx.Label):
    @flx.action
    def new_text(self):
        self.text('')

class Pstat(flx.PyWidget):
    def init(self):

        super().init()

        with flx.VBox():
            with flx.HBox():
                self.label_sheet_name = flx.Label(flex = 0.2 , text = "Excel Sheet :")
                self.input_sheet_name = flx.LineEdit( placeholder_text = "Enter number" )
            with flx.HBox():
                self.faq_btn = flx.Button(flex = 0.45 , text = "Data1")
                self.calcs_btn = flx.Button(flex = 0.45 , text = "Calcs")

    @flx.action
    def read_pd(self):
        xw.view(self.info)

    @flx.reaction("calcs_btn.pointer_click","faq_btn.pointer_click")
    def info(self,*events):
        if events[-1].source.text == self.faq_btn.text:
            file_in = flx.App(FileViewer).launch()
        else:
            file_in = None
        return file_in

app = flx.App(Pstat)
app.launch()
flx.run()

I need on touch "faq_btn" to open FileBrowser, choose excel file open it in xlwings and create new Label with pass to excel file.
The only way that i manage to create fileBrowser is to launch FileViewer in new session. How can i do it in one session? How can pass the path from FileBrowser to Label and read_pd function?

You'll need to reserve a space for the file widget to be in, e.g. in a splitter or hbox. Then you can instantiate the widget and set its parent.
