Split Project Pane in Atom editor - atom-editor

How can I split the Project pane? If I right click on the Project pane, and click Split right/left/up/down the pane is split but I can't add any files into that pane, I've tried to drag and drop some files but it isn't working.
For example, I have split the project panel into 3 parts as marked on the picture below, but the 2 and 3 are empty, how can I move files from 1 to 2 or 3 pane? Thanks.

Load an anchor pane from a main.java in a tab pane

I'm coding in JavaFX. I'm creating a border pane with a tab pane with 5 tabs. When the user clicks in one, the system has to load the specific anchor pane. These 5 distinct panes are created in 5 different main.java, so when I run one of them, it wil load one at a time. My question is: How can I load the anchor pane from the main.java and insert it into the tab pane? Thanks! Sorry for my english

Qt focus changing order

For example we have a groupbox with some amount of lineEdits.
When user press Tab focus from one lineEdit changed to other.
How to make focus change in the specific order?
In my Dialog focus changed in a very strange way. For example cursor jumps this way 1 3 2 4 lineEdits. I want to make it jumping 1 2 3 4 lineEdits
I think that the order is such because I added this line edits in such order...but remaking all GUI is not a solution for me...
In a designer you should select Edit->Edit Tab Order (blue numbers will appear).
Than you click on your widgets in the order you want them (numbers will change).
After you are done, you should select Edit->Edit Widgets (or press F3).
If you are not using designer, use:
void QWidget::setTabOrder ( QWidget *first, QWidget *second );
Qt Designer: Edit->Edit Tab Order

How do I conveniently reveal/expand sublevels in outline view of interface builder dock in Xcode4

I have several table columns embedded in a table view embedded in a scroll view embedded in larger view embedded in a tab view embedded in another view embedded in a window.
When click on the nib file in Xcode 4, the Editor pane shows me the Interface Builder dock in an outline view. Typically, I'd like to set the Cocoa bindings for the table columns.
To get to the table columns, I have to open many levels of subtrees, sequentially. If I click on a column header in the graphical view, and I get lucky, it takes me to the table header. In this case, I only have to open one more level, the table view. When I run my project in the debugger, and come back to the nib file, I have to do it all over again.
Is if there a way to expand all sublevels of the outline view in the IB dock with a single command, or to expand sublevels under a selected level ?
EDIT: Not an answer, but a workaround: double click the nib file to open it in a separate window. The window won't be affected by switching files in the main window. Another feature I was unaware of is Xcode 4's tab capability (Command-T) - works like a tabbed browser.
Hold Command ⌘ Alt while clicking on the disclosure triangle at the appropriate level.
Fast forwarding several years, it looks like with Xcode 11.6, you now hold Option ⌥ key while clicking on the disclosure triangle.

List of modified files in XCode 4

How do I get to see all the local modified files with respect to the sub-version copy as a list?
XCode 3 had a shortcut and a view to show these from where we could commit the code too: cmd+shift+v
I see no alternative to it in XCode 4. Anyone knows how?
Thanks,

In the Project Navigator (the normal source tree view), take a look at the buttons along the bottom edge (to the left of the search filter field). The middle button turns on a filter that shows only files with source control status (uncommitted changes).
Bottom right corner of Filter (selected state) of Project Navigator, their is button for "Show only files with source-control status", by pressing this button it will show only modified files in Project Navigator.
