[Tutor] Dynamic TKinter widgets?

[ALAN GAULD]

CC'ing the list...
 
I know you can use images instead of text with Labels, like you can with Buttons. 
>The advantage of a Text widget, in this case, is that you can use both in the same widget. 
>That way, I don't need to worry about how widgets are displayed, shuffled around, and 
>undisplayed during runtime. One widget should handle everything.

>Don't get hung up on the number of widgets. In the scheme of things widgets are not 
expensive. Create them as you need them, delete them when you are done. Layout 
managers are there to manage the layout for you. if you can define the layout in terms 
of a grid then you can fill the grid with blanks to hold the shape and add/remove 
widgets as you like.

If you use pack you can either force the containing frame to a fixed size or allow it 
to grow/shrink with the widgets. Either approach can work.

This is standard? That's interesting to know. The biggest issue I'm having here is scalability. 
>Each new spread is going to need a new frame widget, which in turn will need 
>(number of cards in spread)*2 more widgets.

>But that's how many? If its getting up beyond a couple of thousand then you might 
have a problem. If its less than a hundred its not an issue. In between you might want 
to be a bit clever.

As noted above, the Text widget solution only needs one.

>Actually it probably needs more. Each image is a widget too, so you just organise 
the widgets inside a Text instead of inside a Frame or Canvas. All these things are 
just containers for more widgets. Frames are designed to hold widgets, end of story. 
Text is designed to *display* images and text - usually within a Frame. Canvas is 
designed to *display* images and graphics shapes. If you want your images joined 
or surrounded by lines/circles etc then go with Canvas. If you need to include 
explanatory text around the images use a Text. If you want to create a reusable 
widget that you can use in multiple screens or hot swap with other variants of 
the same go with a Frame and build a display widget hierarchy. If you just want to 
display a bunch of images it doesn't matter much which one you pick.

I repeat, don't sweat over the widget count, that's not usually an issue.
