[solved] How to increase widget size

edited December 2014 in OpenSesame

Hi, I was wondering how to scale up a check box widget that I create using an in-line python script. For my experiment I use a larger font (32pt) and check boxes appear too small next to their labels. Ideally I'd like to avoid building a custom widget just to get this. Any suggestions are welcome.

    Hi Mitko,

    Isn't set widget_label "<span size=23>WIDGET</span>" what you're looking for?

    Alternatively, you might let your widget span over multiple cells. Unfortunately, I can't really tell how this works. I just saw on the documentation that it is somehow possible.

    Good luck,

    Eduard

    Hi Eduard,

    Thanks for your suggestion. I don't quite understand where I am supposed to enter the text you wrote. I'm creating the widget using python and your suggestion looks more like the standard OpenSesame script. Can I mix the two?

    Also, does your suggestion really scale the check box itself or just its label? The labels that I have are already using the 32pt font size automatically. It's just the square checkbox in front of the label that looks tiny. This is what I'd like to enlarge.

    As a workaround in the mean time, I have the following solution: I made a new python class that inherits from widgets.checkbox and reimplements the render method. Instead of drawing a box from an image (which is what the standard OpenSesame checkbox uses in widgets.checkbox ) I just draw the label preceded with the unicode characters for an empty/checked box

    Here is the code in case anyone is interested:

    class Checkbox( widgets.checkbox ):
        def __init__(self, form, text=u'checkbox', frame=False, group=None,
                checked=False, click_accepts=False, var=None):
            super(Checkbox, self).__init__(form, text, frame, group, checked,
                click_accepts, var)
    
        def render(self):
            mark = u'☑' if self.checked else u'☐'
            self.draw_text(mark + " " + self.text)
    

    Cheers,
    Mitko

    Oh sorry. Apparently, I haven't read your questions. Indeed my suggestions works only for opensesame buit-in forms.

    If you only want the box to be bigger, you could have also just changed the self.box_size variable during initialization of your selfmade Checkbox class, but your solution seems to do the trick as well.

    Sorry again for the confusion. If everything is good now, I will mark this thread as solved, okay?

    Hi Eduard,

    I tried changing the box_size as you suggested, but that only moved the text a little. The actual check box was still drawn the same size as before. Looking at the code in GitHub it seems that both available theme engines right now draw checkboxes with a fixed size (either 16 or taken from the standard checkbox image) and don't care about the checkbox.box_size field.

    Anyway, I'm happy with my current solution. Using the corresponding Unicode characters actually looks quite decent, so I'll stick with that. You can mark this thread as solved.

    Cheers,
    Mitko

    Hi Mitko,

    Your solution is pretty elegant, but for the less Python-savvy I would like to point out yet another solution: You could replace the checkbox images in the resources/widgets/gray/ folder (which is a subfolder of the OpenSesame program folder on Windows).

    Cheers!

  • Hey @mitko,

    I have the same problem with the too small check boxes. I tried the solution from @sebastiaan but it doesn't work so well (sorry :( ). First, the frame around the boxes stays the same size and somehow the larger checkboxes don't click so well. I would be interested in your workaround. Could you maybe go into more detail about how you did it?@sebastiaan

    Thank you!

  • Hi Mirko,

    Can you try to locate the folder that Sebastiaan pointed out? If you find it, you can replace the file in it with another file that contains a checkbox of your liking. Should be a simple image file. On my system (Ubuntu) the files are located here:

    Hope this helps.
