zoomout | pull switch | Video Utils library

So I've got a pretty small div, in which I gotta get a small timeline chart shoved in. The current problem is, that due to the chart being perfectly centered, I have a lot of whitespace I could really use, to make the actual data and chart much larger.:

I think showing the parent div shouldn't matter(because changing around these sizes doesn't really affect the chart itself). It feels like there's some option in the configuration that I'm missing. I've tried setting offsetY and even offsetX to negative values, because I was desperate, but to no avail.

I'm trying to apply a zoom example that I've found on this site but it uses a QGraphicsScene and a QGraphicsView while I should use a simple QLabel. This is the code but it does not work. Can I zoom on a Qlabel or is it impossible? The zoom should work with ctrl++ / ctrl+- shortcut.

I have recently come across a problem with registering an event callback on an svg button. I want to conditionally render the button, but my @click event callback is not registered. This happens even if the condition is initially true. Removing the v-if makes everything work. Is this supposed to happen? What is a workaround for this?

Note: It seems to be working if I don’t use the showControls variable, and instead just supply v-if=true...

Here’s my component code:

I'm creating a songbook app, and I want to be able to zoom in and out the lyrics of songs. I added zoom functions but I want the app to be able to remember what text size the lyrics had before the user left the app. I tried using Shared Preferences but it isn't working.

Here is what I tried so far

I've created a LineChart that has 5 charts. Each has 250 points: 1 point every 1 min. I have a button which moves MinValueX and MaxValueX. And an event UserControl_MouseDown which adds new data to 1 chart. But when I invoke this it needs 15-20 seconds to move or add data to the plot. I think 1250 point isn't a lot. It looks like it draws the entire graph again instead of moving it, or adding new data.

Can I somehow change the rendering behavior to be more optimal?

Here is my LineChart control:

This is a demo app for animations that i am making. It's an application with simple image which should react on button click like rotate, zoom in, zoom out, fade in/out, etc, but instead it crashes, i can't possibly find what can be the problem, i have searched all over the internet for solutions, but with no luck, here is the code:

what i want to do that when i click a button it opens specific modal like when i click button1 it opens modal1 and so on , how can i achieve this :

I am not able to show the XML file in smartphone as it is shown in android studio. In some smartphones bottom space is blank below the ads and in some smartphones it is properly displayed.

Please correct my XML code it is given below. Thanks in advance

I have a QGraphicSscene in a QGraphicsView object. In my scene you can draw ROIs, so I track the mouse position all the time. Since the objects are often not very big you can zoom in on them, I would like to move the displayed scene section when the mouse is at the edge of the displayed scene. With event.scenePos() I get the position of my mouse pointer, but how can I check if I am at the edge of the scene or not?

Zooming in and out functions in my code as follows:
