Hi for some reason I can't find this answer anywhere.
I can't reopen my application when I close it using the application dock, I can only reopen using the tray to set isOpen back to true.
Code in question:
Tray(
icon = TrayIcon,
menu = {
Item(
"Exit",
onClick = { exitApplication() }
)
Item(
"Open",
onClick = {isOpen.value = true}
)
}
)
if(isOpen.value) {
Window(
onCloseRequest = { isOpen.value = false },
title = "Teamcity Desktop",
state = rememberWindowState(width = 800.dp, height = 900.dp)
) {}
After pressing the X button on my application the window for it disappears (naturally). However the odd part is that I cannot find the way to make it reappear when you click the application icon in the application dock on mac os. The only way to make it reappear is to go to the tray and use the "Open" item. Does anyone know how I would listen for or use a application dock click to reopen the app?
Maybe I need to change my "onCloseRequest" strategy completely?
Does node-notifier support allowing the notification stay on the action center until dismissed by user? Timeout and wait attribute is currently not working
it's on depends on os. for mac its provides timeout and wait but for windows, it's not supported by windows.
Here are all notification options :
const NotificationCenter = require('node-notifier').NotificationCenter;
var notifier = new NotificationCenter({
withFallback: false, // Use Growl Fallback if <= 10.8
customPath: undefined // Relative/Absolute path to binary if you want to use your own fork of terminal-notifier
});
notifier.notify(
{
title: title,
subtitle: subtitle,
message: message,
sound: false, // Case Sensitive string for location of sound file, or use one of macOS' native sounds (see below)
icon: 'Terminal Icon', // Absolute Path to Triggering Icon
contentImage: undefined, // Absolute Path to Attached Image (Content Image)
open: undefined, // URL to open on Click
wait: false, // Wait for User Action against Notification or times out. Same as timeout = 5 seconds
// New in latest version. See `example/macInput.js` for usage
timeout: 5, // Takes precedence over wait if both are defined.
closeLabel: undefined, // String. Label for cancel button
actions: undefined, // String | Array<String>. Action label or list of labels in case of dropdown
dropdownLabel: undefined, // String. Label to be used if multiple actions
reply: false // Boolean. If notification should take input. Value passed as third argument in callback and event emitter.
},
function (error, response, metadata) {
console.log(response, metadata);
}
);
I am trying to use sublime text Javascript Beautify plugin, and it says I need to change to below setting:
{
"indent_size": 4,
"indent_char": " ",
"indent_level": 0,
"indent_with_tabs": false,
"preserve_newlines": true,
"max_preserve_newlines": 10,
"jslint_happy": false,
"brace_style": "collapse",
"keep_array_indentation": false,
"keep_function_indentation": false,
"space_before_conditional": true,
"break_chained_methods": false,
"eval_code": false,
"unescape_strings": false,
"wrap_line_length": 0,
// jsbeautify options
"format_on_save": true
}
Where exactly do I have to make this change in sublime text?
All package settings can be accessed from the Preferences/Package Settings menu.
If i create a button as a subview of a label, when i click the button it does not register, the a_share method is never called. How can i create a subview that can be clicked?
button = UIButton.buttonWithType(UIButtonTypeRoundedRect)
button.setFrame [[ 250, 536 ], [ 120, 120 ]]
button.styleClass = 'browse_share'
button.tag = 3
button.addTarget(self, action: "a_share:",
forControlEvents:UIControlEventTouchUpInside)
label.addSubview button
....
def a_share
PM.logger.debug "share"
PM.logger.debug sender.tag
end
Make sure to turn on user interaction for the label, otherwise it won't pass along any taps/gestures:
label.userInteractionEnabled = true
I want to make my app laptop friendly. I can tab to everywhere, but if I tab to a QPushButton I can't press it with Enter, only with space.
What's the problem? How to make it pressable for Enter?
tl;dr
In the Qt Creator's UI view, select the button you want to make pressable for Enter.
In the right side at the Property Editor scroll down to the blue part titled QPushButton.
Check the checkbox by autoDefault or default.
Most of the cases the main different between autoDefault and default is how the button will be rendered. But there are cases where it can cause unexpected things so for more information read more below.
Full review
Overview
Every QPushButton has 3 properties that are not inherited. From these, two (default and autoDefault) have a major role when we place buttons on QDialogs, because these settings (and the focus on one of the buttons) decides which button will be pressed if we hit Enter.
All of these properties are set false by default. Only expection is autoDefault that will be true if the button has a QDialog parent.
Every time you press space the button with the focus on it will be pressed. The followings will describe what happens if you press Enter.
Default property
If this is set true, the button will be a default button.
If Enter is pressed on the dialog, than this button will be pressed, except when the focus is on an autoDefault button.
There should be only one default button. If you add more then the last one added will be the default button.
AutoDefault property
If this is set true, the button will be an autoDefault button.
If Enter is pressed on the dialog, than this button will be pressed if the focus is on it.
If the focus is not on an autoDefault button and there is no default button than the next autoDefault button will be pressed for Enter.
Flat property
If this is set true, then the border of the button will not be raised.
Example tables
The following tables show which button will be pressed with different buttons on different focus. The buttons are added from left to right.
Test code
The following code is a way to add buttons to a dialog. It can be used for testing by changing the boolean values at setDefault() and/or setAutoDefault().
You just need to create a window, add a QPushButton called pushButton and a QLabel called label (that is the default naming). Don't forget to #include <QMessageBox>. Then copy this code to the button's clicked() signal:
void MainWindow::on_pushButton_clicked()
{
QMessageBox msgBox;
QPushButton button("Button");
button.setDefault(false);
button.setAutoDefault(false);
msgBox.addButton(&button, QMessageBox::ActionRole);
QPushButton autodefaultbutton("AutoDefault Button");
autodefaultbutton.setDefault(false);
autodefaultbutton.setAutoDefault(true);
msgBox.addButton(&autodefaultbutton, QMessageBox::ActionRole);
QPushButton autodefaultbutton2("AutoDefault Button2");
autodefaultbutton2.setDefault(false);
autodefaultbutton2.setAutoDefault(true);
msgBox.addButton(&autodefaultbutton2, QMessageBox::ActionRole);
QPushButton defaultbutton("Default Button");
defaultbutton.setDefault(true);
defaultbutton.setAutoDefault(false);
msgBox.addButton(&defaultbutton, QMessageBox::ActionRole);
msgBox.exec();
if (msgBox.clickedButton() == &button) {
ui->label->setText("Button");
} else if (msgBox.clickedButton() == &defaultbutton) {
ui->label->setText("Default Button");
} else if (msgBox.clickedButton() == &autodefaultbutton) {
ui->label->setText("AutoDefault Button");
} else if (msgBox.clickedButton() == &autodefaultbutton2) {
ui->label->setText("AutoDefault Button2");
}
}
Display
If you compile the code you can get this window. You doesn't even have to click to the buttons because the way they are rendered by the OS shows which one will be pressed if you hit Enter or space.
Official documentation
Most of this answer was made according to the official documentation.
The QPushButton documentation made by Qt states these:
Default and autodefault buttons decide what happens when the user
presses enter in a dialog.
A button with this property set to true (i.e., the dialog's default
button,) will automatically be pressed when the user presses enter,
with one exception: if an autoDefault button currently has focus, the
autoDefault button is pressed. When the dialog has autoDefault buttons
but no default button, pressing enter will press either the
autoDefault button that currently has focus, or if no button has
focus, the next autoDefault button in the focus chain.
In a dialog, only one push button at a time can be the default button.
This button is then displayed with an additional frame (depending on
the GUI style).
The default button behavior is provided only in dialogs. Buttons can
always be clicked from the keyboard by pressing Spacebar when the
button has focus.
If the default property is set to false on the current default button
while the dialog is visible, a new default will automatically be
assigned the next time a pushbutton in the dialog receives focus.
It's also worth to check QDialog and QMessageBox.
According to Qt's documentation Enter should work
Command buttons in dialogs are by default auto-default buttons, i.e. they become the default push button automatically when they receive the keyboard input focus. A default button is a push button that is activated when the user presses the Enter or Return key in a dialog. You can change this with setAutoDefault().

totymedli's answer is great. I added a small program to test various combinations of isDefault, autoDefault, setDefault and setAutoDefault functions.

super(Window, self).__init__(parent)

defaultInitialState = False
self.lineEdit1 = QLineEdit(self)
self.lineEdit2 = QLineEdit(self)
self.lineEdit3 = QLineEdit(self)
# if we create a new button (e.g. "Print state"), with the same function,
# it doesn't work, because adding a new button (apart from our 3 buttons)
# produces total mess, so we use this lineedit for this purpose
self.lineEdit1.returnPressed.connect(self.printState)

Set the tab order for your widgets. This will allow usage of return key for clicking. Its in there by default inside Qt.
