Hi,

In wxPython 4.0 Phoenix, I'm trying to use wx.html2.WebView with a
screen reader.

Whether with JAWS or NVDA, I have to make a left mouse click on the
WebView to be able to see my page in an accessible Web interface,
('Internet Explorer_Server').

Here is my code using the SetPage method, but know that I'm having the
same problem with LoadURL.

You'll find in attachment, an other code that uses the
user32.mouse_event to simulate the left click once the WevView is displayed.

This attached code works perfectly, but it would be better if the
Internet Explorer_Server page is opened without having to make this
click, would it be possible to integrate this into a method of the
wx.html2.WevView class?

Thank you in advance for your answers.

import wx
import wx.html2

class MyWebView (wx.Dialog):

    def __init__(self, parent):
        wx.Dialog.__init__(self, parent)
        sizer = wx.BoxSizer(wx.VERTICAL)
        self.browser = wx.html2.WebView.New(self)
        self.changeBtn = wx.Button (self, -1, label="Change page")

        # The pages that I want to display disposed in a tuple.
        self.pages = (
        "<html><head><title>Hello everyone
!</title></head><body><h1>We're testing wx.html2.WebView with a Screen
Reader !</h1></body></html>",
        "<html><head><title>Second page !</title></head><body><h1>This
is a second page</h1></body></html>",
        "<html><head><title>Third page !</title></head><body><h1>This
is a third page</h1></body></html>"
        )

        self.index = 0
        self.display = self.pages[self.index]
        sizer.Add(self.browser, 1, wx.EXPAND, 10)
        sizer.Add(self.changeBtn)
        self.SetSizer(sizer)
        self.SetSize((700, 700))

    # Events.
        self.changeBtn.Bind (wx.EVT_BUTTON, self.onChangePage)

    def onChangePage (self, evt):
        self.index += 1
        if self.index == len (self.pages):
            self.index = 0
        self.display = self.pages[self.index]
        self.browser.SetPage(self.display, "")

if __name__ == '__main__':
    app = wx.App()
    dialog = MyWebView (None)
    dialog.browser.SetPage(dialog.display, "")
    dialog.Show ()
    app.MainLoop()

Kind regards,
Abdel.
