Exclamation point in top right of windows - over the close button - java

When I open some Java applications, especially examples launched from Java Web Start, I will often see an exclamation mark next to/covering the close button, depending on the window size. It is a bit worrying actually.
What does it mean, and what is its function?

It means the app. is sand-boxed.
The function of it is to inform the user that an app. is running that is sand-boxed.
See Exploring Security Warning Functionality for more details.
It is supposed to be a bit worrying, actually. Don't go typing your bank account details into one of those floating windows that looks 'something like' your bank log-on. ;)

Java AWT Window management, user input, and focus?

I'm trying to hunt down the source of a bug that relates to window management, and possibly awt specifically. However, I have little to no familiarity with window management in general, or awt, so I'm even sure what I searching for. I'm hoping for some general guidance on terminology or otherwise that might help guide me in the correct direction.
In the program I am working on, the user can open windows that can be interacted with (i.e. they have text input boxes, drop down menus, etc) and windows that cannot be interacted with (i.e. they just display dialog). When the user opens a "non-interactive" window, the user can still use the underlying program. However, when an "interactive" window is opened, the user is blocked from using the underlying program until the window is closed. Additionally, "interactive" windows seem to stack themselves on top of "non-interactive" windows. That is to say, if I open a "non-interactive" window and then open an "interactive" window after, the "interactive" window will place itself on top of the "non-interactive" window and won't allow the user to use any of the title bar widgets. In this program, this behavior is not always desirable.
I assumed that this would have something to do with focusing, but I read through this document without much luck (this could be that I just don't know what I'm looking for). Particularly, I noticed the mention of "VetoableChangeLister" which doesn't seem to appear anywhere in the code I'm working with, as well as the method "requestFocusInWindow", which does appear in the code I'm working with but not in any way that I could see that relates to my above problem description.
Would the above problem be related to window focusing? Or am I barking up the wrong tree here? If nothing else, even some basic terminology so I can at least Google search intelligently.
The question I was asking relates to the "modality" of windows and was answered in the comments. The link provided explaining modality is https://docs.oracle.com/javase/tutorial/uiswing/misc/modality.html

First "hello, world" test case in Eclipse from LeanFT 14.50

I try to create my first test case in LeanFT for that I downloaded from Microsoft Store - One Note app. First of all I would like to learn how to press a button, for example "Home" button.
I tried to select "Home" menu using Object Identification Center (OIC) but I couldn't create identifications for that menu - it seems that OIC doesn't see "Home" menu and highlight a much larger area -
Are there any features how to work with apps from Microsoft Store?
Are there any features how to work with apps from Microsoft Store?
Yes.
But, that's not really what you're asking.
As you probably saw in LeanFT settings, there are multiple technologies available, most of them disabled.
If I remember correctly, by default the ones enabled are WPF, STD Win, and some other.
What are these technologies?
They are the ones in which the app (the AUT) were written.
You need to know this information if you want to use LeanFT, OIC, etc.
So - the first question you need to ask is: In what technology is my AUT (OneNote in your case) written?
The next question is: Is this technology enabled in settings?
After you enabled it and restarted the engine so that the technology can be taken into account - then you can start using the OIC.
And I suggest only keeping enabled the technologies needed. There's only so much guessing the engine can do. If you have only one tech enabled, the engine knows exactly what you need.

How to keep taskbar bottom of other windows?

I try to make an application which must be full screen. But when i press CTRL+ALT+DEL task manager comes up. Even i disable task manager, at this time its error message comes up and make taskbar visible. Then user get the chance to go to the dekstop but i dont want user to get this chance. Only user could be able to go to desktop when it did what application wants from it. So i need taskbar keep bottom of other windows until user does what it should do. And i need to do this by my application which i try to code in Java
How can i change the status of task bar using registry?
Why not permanently disable the taskbar?
Follow this link to permanently disable the task bar.
You can edit .reg files in Java, follow This link to know how to edit .reg files
"But how can i do it by java without reseting the machine?"
As far as i came across, you have to reboot your system, no way out.
Ok i found it.
When i changed the value of 8th byte value of Settings variable to 10 in
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\StuckRects2
in registery
It just deselect the "Keep the task bar on top other windows" option
For applying the changes explorer.exe should be killed and re run
There are key strokes which Windows catches before they are sent to application and Ctrl+Alt+Del is one of those.
Regarding "Then user get the chance to go to the dekstop", if you set frame.setAlwaysOnTop(true);, user won't be able to switch to other any application.
You can use java's fullscreen API, and then use a Robot to force focus back to your application. See here: Java Full Screen Program (Swing) -Tab/ALT F4.
Good luck in whatever you are doing - it doesn't sound fun!

Alternative to clipboard for sharing data between a web based application and legacy desktop application

I've been pondering over this problem most the afternoon and haven't yet found the most ideal solution so thought I would see what others think..
There is a legacy Win16 application that has to be modified (with the least effort) in order to communicate with a web based application.
The idea is such that in the Win16 app, the user will want to look up a specific code, so they'll click a button which will then launch the browser and allow them to navigate a specific set of pages until they find the result they desire, then they have the option of either pressing Select or Cancel.
Pressing Select should pass back a small string back to the app (around 10 characters) and close the browser. Cancel will likewise send a Cancel message back to the app and again close the browser window.
I can't see many choices available in implementation as the Win16 app is not able to call webservices, so I'm looking at using the clipboard, however that is not without problems.
I hope there's some other alternative I haven't thought of,
As always - all advice appreciated.
Thanks,

How can I stop using a mouse while programming in my IDE?

I love using an IDE, because I get some great productivity gains. However, I have a couple reasons to stop using a mouse with an IDE:
To code faster - It definitely slows down my coding when my typing is interrupted with all of the constant point and clicking.
To relieve pain - I've never had pain from the keyboard, but I get tendinitis from the mouse.
I've got my cheat sheet for my IDE printed out and now I'm ready.
What's the best way get off the mouse?
Are there any hurdles that I'm going to run into?
Are there any tips for specific IDEs (Visual Studio, Eclipse, etc.) ?
Move it to the wrong side (eg if you are right handed then put it on the left of the keyboard). That way, you can still use it if necessary, but you should find you aren't using it unecessarily.
If changing sides isn't enough to confuse your brain, then moving it to a place where it is accessible but you have to think before reaching for it. As long as you can't reach for the mouse without thinking about it, then you will find that it is easier to use keyboard shortcuts instead. Essentially you want the mouse to be an option but the keyboard to be a better/easier/more convenient one!
As for pitfalls, well you may find that if you have to test any interfaces (web based or dektop) that you need to revert back to using the mouse. Also I find that if I have to work outside of the IDE, then it is just not as efficient to do without the mouse. Often we use WOrd for specifications and documentation, and trying to get away with using that without a mouse, is tricky (in my experience).
Another potential source of annoyance, is when switching between applications (Eclipse, VS, etc), you find that they often use different keyboard shortcuts, and so it can take a while to get back up to speed again, or you have to spend some time reconfiguring the shortcuts to be consistent.
Unplug it.
If your mouse is completely gone then you will be forced to learn how to live without it and therefore will become productive without it.
Anytime you're about to use the mouse, forcibly stop yourself and look up the keyboard shortcut for that operation. Do that a few times per operation and soon your muscle memory will kick in and you won't even have to think about it anymore.
Learn the keyboard short cuts :)
Also some editors are better suited for mouse free operation. I use ViEmu with Visual Studio which has helped me reduce, but not eliminate the need for using the mouse.
Get a trackball.
Your real question is about pain and productivity, the mouse is just a by-product of your circumstances. I would rephrase the question to reflect your real purpose.
Check out the wrist braces. I've heard from people that it makes a huge difference.
For VS, check out Sara Ford's blog.
Bind Macros to Keyboard Shortcuts
Keyboard Shortcuts to navigate task list
Search her blog for plenty of other tips and tricks.
Use the command line whenever you can (Install Powershell)
Switch to vim or emacs for code editing (or use ViEmu if you really need the intellisense)
If you develop web applications and/or spend a lot of time on the web, get the Vimperator or Firemacs extensions
Learn keyboard shortcuts for everything else.
???
Profit!!! (from your increased productivity)
Hide the mouse under a copy of your cheat sheet.
For visual studio I use the ViEmu plugin that allows you to use vi commands in visual studio. It's a bit difficult to get the hang of it but once you're done you'll only be using the mouse on the designer.
Get a webcam and eye-tracking software. Then you can fix bugs just by looking at them. It makes you feel all-powerful.
I've summed up some shortcuts that will get you working faster with Visual Studio in my blog.
I recommend you start at this article, that shows you the shortcuts I'd recommend you should get to know first...
Switch to emacs.
Open the nearest drawer and shove it in and close the drawer. That way, when you really do need it it'll be inconvenient to use it!!!
Also, if you're using multiple IDEs it pays to configure key bindings that are common across them, so that you can switch between them easily.
Change your keys to Emacs setup , Learn the Keyboard Shortcuts. I rarely use the mouse, if ever, in eclipse. i find it alot easier to just use emacs key short cuts.
When I contracted for an investment bank in NYC, there was this guy who didn't use a mouse. He was a java/kdb dev and just used vim. I used to think it was the strangest thing that he didn't have a mouse attached to his computer, but damn.. that guy was productive. Probably the most productive guy I've ever worked with.
So yea, if you really want to go that route you could try using vim, or something similar. You'll lose the features you're used to in your IDE, but it worked for him...
Become a better typer. As a slow
typer, I find myself going to the
mouse so I dont have to type. If I
were more efficient at typing, I would
be less inclined to use the mouse.
If you are using a laptop and a
mouse, remove the mouse and leave the
trackpad as your only option. That
will be so painful that you will be
forced to learn more keyboard
shortcuts.
Some very good answers above.
I spent a while injured with RSI and mousing was an issue. I already used shortcuts a LOT.
But coding using strictly the keyboard was definitely slower, especially when it comes to navigating around the code.
As I was using vi at the time, I would primarily move around the screen by doing searches for text at the location I wanted to go to; this is very fast, assuming you pick unambiguous text. Leaving line-numbers on and then going to the line number is another way to rapidly navigating. Judicious use of code folding (available in many IDEs) helps, too.
Finally, consider an alternate pointing device. A trackpad sucks for games but can be more accessible for coding, especially if you put it in easy reach of the keys (e.g., if you use a split keyboard, between the two hands). Try switching between two or more styles of device, to avoid injury because of one specific device. And don't ignore wrist pain! Treat it before it gets worse and you end up non-productive for a year or something.
Configure your IDE to use VI or EMACS keyboard controls (and learn them.) Both options allow you do do most tasks without moving your hands of the home row. You'll see your productivity drop during the learning curve but jump way up after as you save a lot of time by not moving your hand of the keyboard to use the mouse.
As a side note, learning to use a terminal based editor is a good skill to have in case you ever need to remotely administer a *nix machine. It will save your bacon some day.

All these coders and no one suggested to write some code to hide the pointer when the IDE's window is active??
Great question... A co-worker suggested Launchy to me as a way to reduce mouse-use/be more productive. It searches your Start Menu (or non-windows equivalent) for apps, docs, shortcuts, etc. Type alt+spacebar to bring up its prompt where you type what you want to launch. Here are a few examples - what you type depends on other things in your Start Menu.
ch for Chrome, f for Firefox
ca for Calculator
expl for Windows Explorer
A power-user can fiddle with its settings to get more out of it but even basic users will benefit from it. Hope it helps.

Hide your mouse - at least one arm's length away - then you can always get it back in an emergency
Move it far enough away that it's inconvenient to use, while your cheat sheet is close enough to easily lookup whenever you are in doubt about how to do something. I would not suggest unplugging it, since it is a useful tool for some operations, such as moving files around. I find drag and drop in some sort of tree like file system view is much easier than the alternatives. The majority of editing operations though, are quickly accomplished via key strokes once you remember them.
I am using IntellijIDEA IDE. There is one very annoying plugin - "Key promoter".
For every mouse-inited action it shows annoying alert with keyboard shortcut which you could use to do the same action.
Well, it took about 2 or 3 weeks for me to stop using mouse at all. It was hard to not turn it off (plugin), but very useful :)
IMHO the best answer is combination of two already given answers:
Print out the keyboard shortcut cheat sheet of your IDE and tape it to the wall next to the screen.
Unplug it. Also this makes a bit harder to procrastinate by switching to SO in the other window...
You may also want to consider doing your coding on a Macbook/Macbook pro. I generally HATE touchpads, but I've had to do some coding on the plane and the new touch-sensitive pads are actually really convenient. For example, you can do things like scrolling with a flick of two singers, and it's a lot more accurate.
It may not be perfect, but it might help with your hands.
I don't think avoiding the mouse completely is practical (you need things like hovers, etc.)
First off, don't try to do everything with a keyboard, start by forcing yourself to use keyboards for the top 3 things that you do all the time. Get the biggest bang for your buck/effort and you will quickly want to use more.
Keep a sheet of paper near by where you write down keyboard short cuts you use. (Alternatively, add this to a company wiki so others can benefit.)
Pay attention to menu items, they frequently have keyboard short cuts.
Find out the keyboard shortcuts that show all other keyboard short cuts.
I use Eclipse all the time, there are several keyboard short cuts that I find invaluable:
CTRL + SPACE - Content Assist
CTRL + 3 - Open any UI Element in eclipse by typing
CTRL + SHIFT + T - Open by type (Uses Capital letters to do word searches and * for wild card, for instance NuPoEx would find NullPointerException)
ALT + SHIFT + R - Rename current selection
ALT + SHIFT + T - Refactor Menu
And CTRL+SHIFT + L gives you a list of all keyboard shortcuts
