I am looking to achieve the following :
when an application stars up, I want it to slide in from the left of the screen
Is this possible to do in linux ? How do I go about achieving it ? I could not find any resources online, so if anyone could point me in the right direction, that would be great.
I am open to programming a solution for this too. It would be great if i can get an answer on how to program something like this.
Presumably you have control over the placement of the window. Place the window off screen, then set up a loop that moves it over one pixel at a time. Exactly how to do that depends on your GUI toolkit.

I want to write something like a taskbar/dock/panel(like tint2,...) with pyQt5.
I know how to write regular GUI applications with it, but my tiling window manager(herbstluftwm) maximizes my panels and openbox makes them resizable etc.
My question : How can I make pyQt show my application as a panel instead of a window? I haven't found anything about that in the documentation.
Thank you.
Thanks to musicamente's help, i could find that the function setWindowFlags() is what I need. It allows to change the behavior of a window.
A website explaining this function is https://pythonprogramminglanguage.com/pyqt5-window-flags/
Trying to use AndroidStudio (3.4.2) for the first time and it appers to be substantially different to the tutorial at
https://developer.android.com/training/basics/firstapp/building-ui
For example:
There is no layout editor toolbar let alone a show button.
There is no autoconnect button
It doesn't show any wiggly lines from the middle of the blue square to its edges.
When adding a text box it goes to the top left and can't be moved.
WTF is going on? This is awful!
So I know this may sound like the hard answer, but in the long run it will make life 1000x easier.
You need to learn XML to design the activities. It's fairly simple and really easy to research. The reason the textbox can't be moved is because the default layout is ConstraintLayout. In order to fix this, go to the xml file and change the Constraint layout to either Relative layout or Linear Layout. In the end, its more simple to learn straight xml.
I suggest you learn Android programming from here or somewhere else because the Android documentation can be confusing especially for a beginner like yourself and trust me, I've been there.
Since the release of javafx 8 is coming up right around the corner, I figured now would be a good time to get better acquainted with a few of the new features. First on my list: enhanced (true) 3D shapes and rendering! Working for an engineering company, being able to integrate a rich 3d environment into some of our visualizations will be great!
In any case, I was working through the 'getting started' here and all was well. Able to compile everything, getting familiar with how they structure all of their layouts in 3d, etc. etc. It was great! After familiarizing myself with some of the more advanced translations, I decided to take a look at their final 'sample 3d application' that had things like mouse and keyboard listeners to set the angle and orientation of the camera, which was the only thing I hadn't done yet. (you can find a link to the source code I downloaded for it, complete with a nbproject here It's called MoleculeSampleApp.zip and it's in the top right corner of the page).
So I go to compile it, everything shows up just fine, the molecule, the axis, and then I try to initiate any action at all, a mouse click, drag, a recognized keyboard input, etc. Everything on the scene simply vanishes.
Well that's strange, I think to myself, so I take a look at the code. Everything looks to be in order, and a few print lines later, I find out that the contents of the graph aren't disappearing until the very END of the listener, whenever that happens to be. Nothing inside of the listener is actually causing the disappearing (unless of course it's the hide/show keyboard shortcuts).
To be honest, I'm a bit baffled by this. There are no exceptions being thrown, no errors printing out. It just disappears, and that's the end of it.
If anyone has any idea why this is happening I would be immensely grateful. It's worth noting, I'm using the javafx 8 developer preview b132.
(if you would like me to post the entire source here, let me know, it's only about 600 lines altogether, but that's pretty heavy for a SO question so I'm just going to leave the links for now).
tl;dr
The moleculesimpleapp.zip located here makes everything disappear on any action it knows to listen for, with no clear reason, why?

Well, simple situation. Is it possible to detect if a user has a dual monitor setup from a web application?
If this is possible, is it possible to open a child browser page on this second monitor, so the new window doesn't overlap the old one?
Reason why I ask: I'm working on a web application and at home I have a dual-monitor system. When I go to the administration part of this site, I want it to open in a new browser, preferably on the other desktop. Of course, I could just click, then drag the new window, but doing this automatically seems more fun. :-)
Don't think JavaScript has the proper functions for this. How about Java itself?
I don't think you'll be able to directly detect a dual monitor setup, but you can probably make a good guess by looking at their screen resolution, using javascript's screen.width and screen.height. If the ratio of the width to the height is 8:3, its a good chance they have 2 standard 4:3 monitors side by side. You can do a similar calculation for 16:9 or 16:10.
Using maxpower47's suggestion about resolution, the only way to display the page on the other monitor would be to open a popup, and use the options to set the top, right, width and height properties so the window will appear on the second monitor in a decent size.
Here is a link that describes how to do this: http://www.netmechanic.com/news/vol4/javascript_no7.htm
I'd like to write a Linux screen magnifier that's customized to my liking. Ideally, the magnified window would be a square about 150 pixels wide that follows the mouse cursor wherever it goes.
Is it possible to do this in X11? Would it be easier to have an application window that follows the mouse around, or would it be better (or possible) to forget about the window altogether and just make the mouse pointer a 150x150 square that magnifies whatever's underneath?
Look at the source to xeyes?
This actually already exists, it's called Xmag (do a Google search for additional info). You might want to check out the source code for it if you want to know how it works.
EDIT: looks like I misread your question a little bit... if you want a magnified square to follow the mouse pointer around, I suppose it should be possible, but I don't know the technical details of how you'd do it. Regardless, the place to start is probably by looking at Xmag as a starting point.
I am unsure if this can run as its own app or would have to be integrated into your window manager. Either way, you would need libx11 (might have a different name from distro to distro). Also, I would suggest taking a look at swarp. I know this is not even close to what you are talking about, but the source code is only 35 lines and it shows what can be done with libx11.
I would personally make that a frameless window that always stays atop with a 1px hole in the middle. The events that the user makes (Mouse clicks, keypresses, whatever) is passed to the window below.
And when the user moves it's cursor it is ought to be visible to your window and you just move it over a bit. For the magnifying part, well - that is left as an exercise to the reader (Because I do not know how to do that as of yet ;-).
Texworks comes with such a feature to inspect the pdf resulting from typesetting a latex source. You can also choose between a square or a circular magnifier. See https://www.tug.org/texworks/ for access to the code which can serve a launchpad.
