I am binding a ListBox to a List in the ViewModel named FilmeSerienListe. SelectedItem is set when ismouseover = True. The SelectedItem of the ListBox is bound to a Property in the ViewModel named SelectedFilmSerie.

This means when the mouse is over a particular ListBoxItem, this ListBoxItem is selected and its value bound to SelectedFilmSerie. BUT this does not seem to work very well, because the SelectedFilmSerie Property is for some reason always NULL. So, I debugged the App to see what did go wrong – Now the weird behaviour – SelectedFilmSerie is in fact NOT the WHOLE time NULL.

At first – when the mouse is over a ListBoxItem – the value parameter is set to the right Object, and it is NOT NULL, BUT then when I go further with my debugging this SelectedFilmSerie Property is recalled and NOW the value parameter is NULL, which make the SelectedFilmSerie Property also NULL.

I created a register/login page that redirects to a to do list website that I created. However, when you first click on my link, both the login and register forms show up. I only want the sign in form to show up first (if someone needs to register, there is an anchor tag at the bottom of the sign in form that redirects to the register form). What do I need to change in my code to make only the sign in form show up when the link is visited?

Code:

I wanted to create a chess program using OOP. So I made a superclass Pieces, a subclass Bishop, and a UI class GameUI. I created a canvas in the class GameUI. I wanted, that when I instantiate an object bishop in the class GameUI, it shows an Image from a bishop, on the canvas.

The problem is, when I instantiate the Bishop, I don't see any image. So I tried to do the same with a text : instead of using the method create_image from the class Canvas, I used the method create_text, and it worked : I saw a text on the canvas. That means, the problem comes from the method create_image, and I don't understand it.

If I create an Image directly in the class GameUi, it works! but that's not what I want...

So I don't have any error message. I see the canvas (with a blue background), but no image on it.

Here's the code :

I'm having a div which contains 10 images, when any one visit or reload the page any of the 6 images should be displayed in a random arrangement. Finally I come with random arrangements but I can't control the number of images and also the images are going out of the div. Is there any way to show 6 different images when in load the website every time

I havet this codepen: https://codepen.io/sp2012/pen/VwpyWdp . Unfortunately, this code is too advanced for me. The game has three maps. I want to keep only the first map and when the game is finished, if you click on the map the game restarts.

The code follows:

This is the HTML:

It's My Code. My Requirement: if the Window Grows the frame also expands as per ratio in both directions. I am trying with SetSize Policy, but nothing will happen. How to achieve it?

Here is My program. My Requirement: Display frame as mentioned size. But in my code its occupies the entire area. How to resolve it?

I'm making a chess game. I've created a main file with the Tkinter code in a class "Window". In this class, I created a canvas. Then I've created a second file with the name "pieces", where I put the behaviour of the different pieces. In this one, I have a superclass "Pieces", and a subclass "Bishop" (because I haven't created the classes for the other pieces yet)

What I tried first to do, is to create a bishop's icon in the constructor of the class "Bishop". My class "Bishop" has the argument "color", so that, when we create an object "Bishop", we can choose if he's black or white. So I wrote :

I am able to use 2 full viewport div using the following code. Sadly, when I try to add an HD (1366x768) image as the background for the first full viewport div, it breaks everything. I tried to use img-fluid as mentioned in Bootstrap 5 docs

I am using the default HTML template provided by getbootstrap.com as starting template.

It would be nice to know how to make the background image responsive and still keep the 2 full viewport sections intact. Please feel free to ask any other info you would want to know. Thanks.
