What is it telling me and how do I turn this off?
How do I turn this off?
Also I turned this on:
but I still have to click my mouse and hold it to see type info. Anyone know what might be overriding this?
I'm following this:
https://www.jetbrains.com/help/idea/edit-scala-code.html#d211606e205
But what is N/A for mac?
You are inside a block which is passed to a function as an argument for by-name parameter. You may turn off this popup completely or only for arguments in curly braces (block expressions):
Type info popup is probably also missing because of it.

I'm editting a .tsx-file and are reaching upon this bonkers file-formatting:
... If I enlarge the window a bit, then it makes more sense:
But I would still like to change it, so value and onClick aren't aligned all that way to the right. Ideally, it would try to align them with the opening bracket (as they do), unless the opening bracket is more than 35 characters, from the line start. Or something like that.
Now, I assume that it's the TypeScript-formatting that dictates the Code Style for a .tsx-file. But when I open the settings: Editor >> Code Style >> TypeScript then there are BAZILLIONS of settings.
Which leads me to three questions:
Does anyone know what I need to change, so object-attributes doesn't follow the opening-brackets width?
Could I find the name of what I'm looking for, in some smart way? I tried hovering over the massive space, hoping that the little yellow light-bulb could shine some light on, what I was after.
Are there any presets, to be found somewhere? So I don't need to engineer a new Code Style, if I dislike the default.
Make sure that the following option is disabled:
Settings (Preferences on macOS)
Editor | Code Style | TypeScript | Wrapping and Braces
Function call arguments: Align when multiline
NOTE: It is possible that the default value has been changed somewhere since the previous version as I have seen a few questions for the same option but different language (PHP and JavaScript).
HINT 1: Did you know that you can paste your own code in the preview area and start changing options to see how they will affect it? It helps locating the right option a lot.
HINT 2: There is a special popup that shows formatting rules applied to the code. It does not show all possible options but can give you a hint what to look for. To invoke it:
Use Help | Find Action... (or Action tab on Search Everywhere -- they use to be different popups but are using the same popup nowadays)
Type adjust to filer actions
Select and invoke "Adjust code style settings" action
It will give you a popup with applicable rules (it's a limited set: may not list all).
An example for PHP code:
How can I suppress the inspection in Kotlin for an unused variable
val xyz = abc
I get the squiggly line but ALT-ENTER is useless for this, I tried also to create in another method several variables unused and they also lack the ALT-ENTER ability to ignore the warning. Although I have definitely used ALT-ENTER for this in the past, although maybe it was only in java, can't remember.
So I must manually construct it by hand. I've been trying several variations but I can't get anything to work. Please tell me the correct //noinspection or #SupressWarnings to use, thanks
In IntelliJ IDEA, a right-side arrow on an ALT+ENTER context menu (like this: ) means that you can use your arrow keys to navigate further along the menu. In this case, it leads to your answer:
#Suppress("UNUSED_VARIABLE")
val unused = ""
If you do not get the initial context menu (Remove variable '...'), you may have disabled the "Unused assignment" inspection in your current project. You can fix this by going to Settings -> Editor -> Inspections.
Is there a way to tell Intellij IDEA 14 to always show the parameter tooltip that appears when you start writing a function? The problem is that the "bubble" disappears when you exit the parentheses and doesn't show up again when you re-enter.
As far as I know there is no configuration option to always display the parameter tooltip. However you can invoke it manually when you reenter the method using CTRL+P (or ⌘+P on Mac).

I think JetBrains should change this default behavior, or at least add an option for it.
For now, here are some workarounds:
Use CTRLP or make a custom key binding such as CTRL;.
Settings / Keymaps / Parameter Info / Add Mouse Shortcut.
Delete and then retype the opening parenthesis.
In IntelliJ 12, how do I make the popup stop...popping up when I hold Ctrl while hovering over a field/method with the mouse? (see picture)
That is the "Brief Info" action (or at least that is what it is called in the Keymap reference.) To the best of my knowledge (i.e. 10+ years of daily IDEA use including all beta/EAP builds), there is no way to turn it off. Searching the settings for either "Brief Info" or "Info" does not show any pertinent setting. Likewise, searching key mappings for the same does not reveal a mapping. In fact in the keymap settings, you can only map mouse clicks, not mouse pointing (i.e. hovering). You can submit a feature request asking for a setting to disable this feature.
Just put of curiosity, why do you want to disable it? I guess I would never see a case where one would Ctrl+MousePoint unless they wanted to see this. The only case I can think of would be if you disliked it popping up when you go to Ctrl+Click on a symbol. If it is the latter, note that you can use Ctrl+B in place of Ctrl+MousePoint
Try turning off the "autopop" options under /Settings/IDE Settings/Editor/Code Completion.
So I try to get a Visual-Studio-With-Resharper-esque keyboard shortcut scheme in IntelliJ, which involves assigning Ctrl+R, Ctrl+R to "Refactor > Rename". I'm not allowed. Reason: Ctrl+R is "Assigned to [Console.TableResult.Reload] which is still not loaded".
How can I remove the assignment from a function that is "not loaded"? Why is it not loaded and how do I load it?
Some actions are added dynamically, e.g. when you activate version control, corresponding actions are added in different menus, etc. That's why sometimes IDEA knows that actions with dedicated shortcuts may be added, but may be not. It warns about such a situation. The message is not easy to read nor to understand though. Will be fixed ASAP.
