QMovie is not a widget but a container that can play simple animations. You can think of QMovie as a class that handles the inner logic of playing the GIF animation frame by frame. Since getMovie returns a promise, we need to make some changes to the code. After some minor refactoring, we end up with the following. The main function is our entry point. Here we create a window and a label. You can find further instructions here. The result is essentially an array of objects that contain information about each GIF.

First, we create our container widget. QWidget s are essentially empty widgets that act as containers. Next, in order to assign child widgets to the QWidget , we need to give it a layout.

A layout dictates how the child widgets should be arranged inside a parent. Here we choose FlexLayout. Since this is all happening asynchronously, we wait for everything to resolve using Promise. This will be called when the search button is clicked. You can think of this as a way to apply block-level CSS in one go. This is pretty much identical to an id in the web world. Now, when you launch the app and enter something in the search field, you should see whatever you searched for logged to your terminal.

This provides a scrolling view onto another widget. I am using Gifshot to generate an animation. I am successfully generating a "file". However, it seems like the encoding is off. The image that's gets generated is being generated via the following code:. When the above code runs, animation. However, when I open it, the animation doesn't actually exist. I'm not sure what I'm doing wrong. I know that Gifshot returns a Base 64 image. I assumed that was the issue.

So, I tried integrating the SO answer found here. However, that didn't work either. Any help is much appreciated. Try the module base64image-to-file.

The only difference is that the data and end events are listened on the stdout object of spawn. Also we listen to spawn 's exit event to make note of any errors.

Although it says downloading using wget , this example applies to downloading using curl with the -O option too. This method of downloading looks the most simple from coding point of view.

Why exec and not spawn? Because we just want wget to tell us if the work was done properly or not, we are not interested in buffers and streams. We are making wget do all the dirty work of making request, handling data, and saving the file for us. As you might have guessed, this method is the fastest among the three methods I described. So now the question is - which method is the best? The answer - whatever suits your need. The wget method is probably the best is you want to save the files to the local disk, but certainly not if you want to send those files as a response to a current client request; for something like that you would need to use a stream.

All the three methods have multiple options, you choice will ultimately depend on what your needs are.
