I am Java developer and would like to know how I can get the equivalent of a JavaDoc in Xcode when CodeSense is doing its auto-complete? If I hit the ESC button I can get a list of methods etc. but it does not show me the descriptions of what the methods do.
I am new to xcode and mac. Bring your mouse over the method name and press alt + left mouse click to see help. To see full help press alt + double mouse left click.
It's not quite the same, but the close equivalent is Quick Help, accessible from the Help Menu. It's a floating palette that dynamically shows a quick documentation for the method or class at your cursor position.
Just to add to the topic, on Xcode 13 you can invoke quick help by using:
⌥ (option) + mouse click
On any method, function, structure and etc...

In VSCode you can hover over a dart class name and it will give you the documentation comments. How do you achieve this in IntelliJ?
I'm using the community edition.
I have tried the cmd + mouse hover but it doesn't give me the comments
it was an option that isn't automatically selected

In the Settings/Preferences dialog (⌃⌥S), go to Editor | General.
In the Other area, select the Show quick documentation on mouse move checkbox and specify the delay in milliseconds after which the
popup should appear.
IntelliJ display Java code auto-completion suggestions in a drop-down menu after pressing CtrlSpace. All other IDEs manage to display the corresponding Javadoc if available. How to get IntelliJ to do that?
How to see JavaDoc in IntelliJ IDEA? refers to displaying it on a mouse hover event whereas I'm missing the Javadoc from code-completion suggestions.
Once you put a dot and the suggestions appear, press F1 (which is the default shortcut for "Quick Documentation" in most keymaps). The documentation for the currently selected method then appears as a card as show in the image. Then you can either use the up/down arrow keys or start typing the method name to select it. The documentation card will reflect accordingly.
You can also click on the pin icon on top right of the documentation card to expand it if required.
Using IntelliJ IDEA 15, I get these constant and annoying documentation popups whenever my mouse is anywhere in the code window for a decompiled class (from a 3rd party jar). It will popup docs for whatever variable/method/class/anything happens to be near my mouse. If my mouse is not near any lines of code, it will popup for the current classfile, so basically I can't browse code unless I move my mouse to another window.
It only happens with decompiled classes, not my normal code. How do I stop these?
Go to File>Settings>Editor>General - in the section 'Other', uncheck 'Show quick documentation on mouse move'.
In later versions of IntelliJ, the path is File>Settings>Editor>Code Editing, and it is under the "Quick Documentation" section.
In my cause, 'Show quick documentation on mouse move' was in Editor > Code Editing:
If you want the documentation bubble but not the popup window, do this:
Place your text cursor on some text which causes the popup.
Press ctrl + q (or whatever keyboard shortcut you have for quick documentation) a couple of times until the popup window disappears, the quick documentation will then revert to the "bubble" on hover.
Under the File/Settings/.., at the top search bar, type in for "Quick Documentation", will point to the location.
Press <F1> button to show/hide this pop-up.
In eclipse when I mouse over a variable I see it quick defenition, when I mouse over with shift pressed, I see full defenition. But in idea, I always need to press some keys to do anything. Is there a way to simplify those tasks in idea?
The quick definition features is accessible with the shortcut ctrl + shift + I.
I don't think it's possible to access to it on a key + the mouse over.
You can edit the idea.properties found in the bin folder of IntelliJ application and add this line:
auto.show.quick.doc=true

This will give you the JavaDoc when hovering over a variable:
In EClipse if I hold the mouse over a class name I get some hint like the picture below about it:
But with doing the same I don't get that hint box in IntellijIDEA.(Mac edition)
Is there a setting somewhere to set this? It is really helpful.
For anybody new finding this question there is also an option for it
You can press CTRL + Q when hovering above a class name to show a popup with more information.
To know the classname and it's initial declaration within the scope, use Ctrl + J (Mac OS)
