move between panels with the keyboard in atom - atom-editor

In atom, I often have multiple panels for different files, and I also have some panels for in-editor terminal. Is it possible to navigate between panels (change the focus) using only the keyboard?

go to Keybindings and check window:focus for changing panes window focus
cmd-k-down window:focus-pane-below
cmd-k-right window:focus-pane-on-right
cmd-k-left window:focus-pane-on-left
cmd-k-n window:focus-next-pane

Handling keyboard navigation in nsDialogs

I'm using nsDialogs to create a custom page in the installer of my app, where users can decide between standard and portable installation.
For this, I create two radio button controls via NSD_CreateRadioButton so that users can decide between the two installation modes.
After receiving feedback from blind users, I'd like to add the possibility to navigate via keyboard between those two radio buttons. So far, pressing the Tab key navigates directly to the next button in the lower navigation bar and not to the . Arrow up / Arrow down have no effect.
How can I add this possibility for keyboard navigation using nsDialogs?
If you use the ${NSD_Create*} macros in nsDialogs.nsh then the WS_TABSTOP style will be set for button controls and you can Tab to them. However, the tab order is: the bottom buttons before the buttons in your dialog.
Assign a access key to allow a user to access a control directly. You do that by adding a ampersand (&) to the text label before a specific character:
${NSD_CreateRadioButton} 0 13u 100% 15u "Click &Me" ; Activate by pressing Alt+M
Pop $0
${NSD_CreateRadioButton} 0 30u 100% 15u "&Or Me"
Pop $0
The arrow keys should also work once one of the radio buttons have focus. The WS_GROUP style also plays a role in keyboard navigation if you have multiple groups of unrelated radio buttons.
I've found a solution to this problem, by experimenting with the suggestions #Anders provided.
In between the two calls to NSD_CreateRadioButton I had another call to NSD_CreateLabel which apparently mixed up the grouping between the two radio buttons.
When I create the radio buttons by two subsequent calls to NSD_CreateRadioButton and then add the describing labels, navigation via Arrow up and Arrow down works. If there is another call to NSD_Create* in between, it breaks the grouping.

Tmux current pane indicator when focus regained

I'm trying to create a visual indicator of which pane is currently focused in tmux when my terminal (iterm2, OSX) window gains focus. I have found that iterm2 sends a focus gained escape sequence (^[[I) so now I am trying to find how I can capture that and fire the prefix q command which shows pane numbers with the active pane in red.
Any ideas on how to capture the escape sequence in tmux OR in iterm2?
I have a partial solution to my issue which takes a different approach. Since I usually have vim and one terminal pane open, dimming vim when it is not focussed is a good indicator which pane is active. In order to achieve this I have modified the vim-diminactive plugin to react to focus events (https://github.com/blueyed/vim-diminactive/pull/8), this requires the Vitality.vim plugin as well as enabling (focus-events) in tmux options.
In order to completely solve my issue I am working on changing the background colour of terminal panes when they lose focus. I use zsh so I can capture the focus event with bindkey (I have verified this works) to issue a background colour change escape code to iterm2, however this seems to have no effect in tmux.

QT strange GUI Components: Tabs?

I saw once someone making the GUI in QT and he had something I have never seen until now: They looked like big buttons one after another and when you clicked on them, the buttons below were going down, making space for the dialog or tab. It was like, if you click on the button "Draw", suddenly below the button a tab or a dialog or ??? appeared with all the GUI components (radio buttons, listboxes, ...) that you need for draw. When you clicked on another button, this GUI disappeared to make space for another GUI. Does anybody know what it is?
Qt does support tabs.
They are actually different widgets you can switch from in the same window.
Here you can find an example on how to use then: http://qt-project.org/doc/qt-4.8/declarative-ui-components-tabwidget.html
Inside a tab it's just like a normal widget.

Qt / How can I have subwindows without losing the main window focus?

I have a main window (on MS Windows) and I want to have sub windows or subpanels with free screen movement. I can use dialog and Qt::splashscreen flag, but when I am on these subwindows I lose the focus caption for the main window. Is there any trick to do what I want? (Something like a multi-focus...)
Maybe it is impossible?
I'm not sure what you mean by losing the focus.
When I create an application with multiple windows, this is what I do: in the sub-window widget, I set the parent to the main window, and set the Qt::Tool flag. It has multiple effects: the window manager sees it as one window, and when you focus any window, all the windows raise.
Do you want QMdiArea? Or a focus proxy?
In Qt, all top-level windows are independent, none is the "main". If you want to nominate one as a main window and have it steal focus from the others, then you will have to implement that manually.
Sounds like you just want to have widgets that you can move around freely on a parent widget/window, without invoking the "window focus changed" event between native Windows windows (...).
I'm not sure if there is a ready-made solution for that, but adding some grab/move/resize events to a widget's edges shouldn't be that hard, or?
I'd simply catch mousedown/up events on certain areas (these should probably be widgets of their own with a link to the parent movable widget), and have them resize/move the window when the mouse moves.

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.
