Form loses focus after OpenDialog closes

[zeo101]

Hi everyone, I wrote a small multi form program to stamp, split or combine pdfs using pikepdf: These forms are called using:

def openStamper(self, Sender):
   form_stamper = Stamper_Form(Application)
   form_stamper.Show()

If I click on "PDF auswählen" an OpenDialog shows up, that lets me pick the file which should get stamped using:

def btn_openpdfClick(self, Sender):
    self.OpenDialog1.Execute()                                              # Show open dialog to pick a file
    self.pdf_path = self.OpenDialog1.FileName                               # Get file path from open dialog
    self.edit_pdf.Text = self.pdf_path                                      # Show PDF path in disabled edit field

After choosing "open" in the dialog, the pdf_path is set correctly according to the selected file, but the stamper window loses focus and disappears behind the next open window on the desktop:

This is really annoying especially when the other program is in fullscreen mode. Is there any possibility to focus the window again after the OpenDialog closes?

Hi @zeo101,

can you share a sample code reproducing this behaviour?

[zeo101]

Hey @lmbelo, I created a small form with delphi 10.4 where I experienced the same behavior as with the multi form programm: opendialog-test-py.zip

Using: Windows 10 Python 3.9.6 Delphi 10.4 Version 27.0.40680.4203 Delphi4Python Exporter 1.2.0 delphivcl==0.1.40
