So you just want to make sure the text isn’t blank? Or you want no trailing or extra blank characters?

If you meant the first:

infoDict = {'Name:': '', 'Attempt:': ''}
while not infoDict['Name:']:
    dlg = DlgFromDict(dictionary=infoDict)

Or if you meant removing all spaces, check this answer on stack overflow:

infoDict['Name:'] = infoDict['Name:'].replace(" ", "")

Hi Daniel,
thank you for the answer.
With the standard settings of the info dialog box, the participant name can be empty. I wold like to force the participants for the name. this is my problem.

OK great, my first example shows an example of how to do this. You are using the coder, and not the builder, correct?

Hello Tomasz,

Instead of using DlgFromDict, you would have to use the slightly more involved Dlg() and pass the ‘size’ argument when you create it, see the docs for an example:

http://www.psychopy.org/api/gui.html

Hello,
there is problem. I checked code like this:
rom psychopy import gui

myDlg = gui.Dlg(title=“My experiment”,size=(800,600))

ok_data = myDlg.show()

but the window was still small :frowning: maybe I did something wrong?

Hello @daniel.riggs1, @tomaszkaczorek,

I intend to use the first code.
\
infoDict = {‘Name:’: ‘’, ‘Attempt:’: ‘’}
while not infoDict[‘Name:’]:
dlg = DlgFromDict(dictionary=infoDict)
\\

But I could not figure out where to insert this code? Please help.

It’s been four years so I’m not sure how much has changed, but if you’re using the builder this would go in a code component.

Hello @daniel.riggs1,

Sorry for not noticing the timeline of this thread. Fortunately, I was able to work around this issue using another process. Thanks anyway :slight_smile:
