Are there any plans on adding in QTreeWidget, QTreeWidgetItem, and QPainter? I love nodegui so far, but I am missing those items for my current project.

Hi, I'm currently working on QTabWidget but I came across few issues that I was unable to easly resolve:

1. I think the node GC is removing entire tabs instance after few seconds of execution? How we can fix it here? How to avoid such issues in the future development?
2. Why is tabWidget1.layout.addWidget(label); not doing its job? The widget instance exists but is not visible inside of the tab pane.
3. Currently we only have FlexLayout implemented and thus lacking any other form of layout, is this something you could tackle, you can handle just initial version of one of them, I'll take over from there handling the rest, if thats possible?

On Ubuntu it gives out this error, could not solve it with #16

Good afternoon,

Thank you very much for this fantastic development! It is allowing me to develop applications very quickly.

I have a problem, I need to create this table but with QTableView.

const table = new QTableWidget(10, 2);
table.setHorizontalHeaderLabels(['ID', 'NAME']);
const cell00 = new QTableWidgetItem('C00');
const cell01 = new QTableWidgetItem('C01');
table.setItem(0, 0, cell00);
table.setItem(0, 1, cell01);
rootView.layout.addWidget(table);

I can't find any examples and everything I try with the Qt documentation gives me errors. Can someone give me an ultra basic example?

I hope you are well and the coronavirus has not infected you. I am infected, but knowing this project makes me smile.

The code I'm using (in a file called index.js):

const { QMainWindow } = require("@nodegui/nodegui");

const win = new QMainWindow();
win.show();

global.win = win; // To prevent win from being garbage collected.

I run it with qode index.js. Maybe because it was compiled with the wrong version of npm or something?? I have no idea. Please help me. Thanks.

Desktop :

• OS: Windows 10
• NodeGUI version: the latest I guess, installed it with npm install @nodegui/nodegui
• NPM version: 6.14.5
• Node version: 12.13.1
• Qode version: 14.2.0

I have a QPlainTextEdit on which I wish to display a random combination of letters, numbers and special characters (a password, basically).

When the text is only letters and numbers, the output runs from left to right with no breaks (as one would expect). It only wraps when it hits the edge of the QPlainTextEdit.

passOutput.setPlainText(
  'AS0dlkqVDmC5L8mKhNAmVU7Ww2j9LiCFo6k43uR6lngZ0Prr2I1xRF7Y64PF92j87V'
);

However, if the text contains certain special characters an undesired line break is inserted. E.g.:

passOutput.setPlainText(
  '2VB#t>ZQyS.*|t`=t=AdB=s9gyNKt%Up9q:fKpL]DKB-5:g),cneAg4(bH:A9hF/cH'
);

Notice the line break after the | character.

My question: is there any way to prevent this?

I would like the text containing the special characters to run from left to right and only wrap when the edge of the QPlainTextEdit is reached (like the example containing just letters and numbers).

I tried styling the QPlainTextEdit using word-break: break-all, but it didn't make a difference.

Looking through the QT docs, I did find this: https://doc.qt.io/qt-5/qtextoption.html#WrapMode-enum

Is something like wrap mode available in NodeGUI?

Describe the bug The flexlayout calculate wrong when deal with complex layout.

To Reproduce

import { QWidget, QStackedWidget, FlexLayout } from './index';

const win = new QWidget();
win.setWindowTitle('demo');

const showMain = () => {
    const rootLayout = new FlexLayout();
    const top = new QWidget();
    const center = new QWidget();
    const bottom = new QWidget();

    const centerLayout = new FlexLayout();

    const stacked = new QStackedWidget();

    const page1 = new QWidget();
    const page1Layout = new FlexLayout();

    const page1left = new QWidget();
    const page1LeftLayout = new FlexLayout();
    const page1right = new QWidget();
    const page1rightLayout = new FlexLayout();

    const page1lefttop = new QWidget();
    const page1leftbottom = new QWidget();
    const page1righttop = new QWidget();
    const page1rightbottom = new QWidget();

    center.setLayout(centerLayout);
    centerLayout.addWidget(stacked);

    stacked.addWidget(page1);

    page1.setLayout(page1Layout);

    page1Layout.addWidget(page1left);
    page1Layout.addWidget(page1right);

    page1left.setLayout(page1LeftLayout);
    page1LeftLayout.addWidget(page1lefttop);
    page1LeftLayout.addWidget(page1leftbottom);

    page1right.setLayout(page1rightLayout);
    page1rightLayout.addWidget(page1righttop);
    page1rightLayout.addWidget(page1rightbottom);

    win.setLayout(rootLayout);
    rootLayout.addWidget(top);
    rootLayout.addWidget(center);
    rootLayout.addWidget(bottom);

    win.setInlineStyle('flex:1;');
    top.setInlineStyle('height:100px;border:1px solid red;');
    center.setInlineStyle('flex:1;border:1px solid green;');
    bottom.setInlineStyle('height:100px;border:1px solid blue;');

    stacked.setInlineStyle('flex:1;');

    page1.setInlineStyle('flex:1;flex-direction:"row";align-items:"stretch";border:8px solid #e8e8e8;');
    page1left.setInlineStyle('flex:1;background-color:white;border-right:8px solid #e8e8e8;');
    page1right.setInlineStyle('width:400px;');

    page1lefttop.setInlineStyle('flex:1;border-bottom:8px solid #e8e8e8;');
    page1leftbottom.setInlineStyle('height:250;');

    page1righttop.setInlineStyle('height:240;border-bottom:8px solid #e8e8e8;');
    page1rightbottom.setInlineStyle('flex:1;');

    win.resize(1366, 768);

    win.show();

    return win;
};

(global as any).main = showMain();

Expected behavior the flexlyout calculate correctly

Screenshots If applicable, add screenshots to help explain your problem.

Additional context when revert flexlayout implementation,it works well,so i think there is some prolbem about throttletimer and performLayout slot

Describe the bug In attempting to determine the source of https://github.com/nodegui/react-nodegui/issues/162#issuecomment-637768503, I rebuilt roughly the same widget structure that nodegui-react should have produced, seen below. This structure displays indeterminate sizing when modifying bits of the layout, just as in the React example.

To Reproduce

import { QMainWindow, QWidget } from '.';
import { QPushButton } from './lib/QtWidgets/QPushButton';
import { FlexLayout } from './lib/core/FlexLayout';

const win = new QMainWindow();
win.resize(500, 500);

const outer = new QWidget();
const outerLayout = new FlexLayout();
outerLayout.setFlexNode(outer.getFlexNode());
outer.setLayout(outerLayout);

const inner = new QWidget();
outerLayout.addWidget(inner);
const innerLayout = new FlexLayout();
innerLayout.setFlexNode(inner.getFlexNode());
inner.setLayout(innerLayout);

const button = new QPushButton();
button.setText('Toggle On');
button.addEventListener('clicked', () => {
    button.setText(button.text() === 'Toggle On' ? 'Toggle Off' : 'Toggle On');
});
innerLayout.addWidget(button);

const centralWidget = new QWidget();
const centralLayout = new FlexLayout();

centralLayout.setFlexNode(centralWidget.getFlexNode());
centralLayout.addWidget(outer);
centralWidget.setLayout(centralLayout);

win.setCentralWidget(centralWidget);
win.show();
(global as any).win = win;

Expected behavior The layout should not vary when modifying non-layout properties of widgets.

After Resizing:

Desktop (please complete the following information):

• OS: macOS 10.15.5
• NodeGUI version: Latest master (0.21.0+)

Describe the bug Font only matches the size of the 100% scaling option from display settings in Windows, but when you move it to more than 100, the font of widgets remains the same size. This makes it near impossible to read without manually scaling (which cannot be easily distributed).

To Reproduce Steps to reproduce the behavior: Run the clipboard image example app on windows 10, don't change anything

Expected behavior The font should scale automatically to match the configured scaling option from windows.

Screenshots 100%: 200%:

As you see, the font of the widgets doesn't scale

Desktop (please complete the following information):

• OS: Windows
• NodeGUI version: 0.21.0
• OS Version 1909

I do not see any way to display Warning, Error or Info dialogs, and the only way right now is to recreate the behavior, which is far from good solution.

Short search on Qt docs shows that there is class exactly for this purpose - QMessageBox. So, any plans to implement it in future?

It'd be great if widgets that accept user input like QLineEdit instances implemented a setValidator method that accepted a function that prohibits input for which it evaluates to false.

For an example of how this is done in PyQt see here.

In JavaScript nodegui it could look something like this:

const { isFloat } = require("validator"); // i.e. validator from npm

//...

const widthLineEdit = new QLineEdit();
widthLineEdit.setPlaceholderText("0.0");
widthLineEdit.setValidator(isFloat)

//...

In the meantime I'm open to workaround suggestions (setInputMask, etc.), I've only just started playing around with nodegui, but so far I'm liking it. Please keep it going. Thank you!

Describe the bug Running an starter application (via npm start) on a cloned (https://github.com/nodegui/nodegui-starter) repository - throws error.

QInputDialog labels and default responses display incorrectly if they are greater than 21 characters long.

Below I show the minimized files that I used, i.e. package.json, tsconfig.json and src/index.js, as well as the sequence of terminal commands that I used to install, build and run the demonstration app. The key lines are near the end of src/index.js.

const messageBox = new QMessageBox( centralWidget );
const okButton = new QPushButton();

// Message box widgets can show messages significantly longer than 21 characters.
messageBox.setText('The message box widget is apparently able to show messages of significant length, and certainly greater than 21 characters.');
okButton.setText('OK');
messageBox.addButton(okButton, ButtonRole.AcceptRole);
messageBox.exec();

// Input dialog widgets correctly show labels and default responses up to 21 characters in length.
// However, labels and/or default responses longer than 21 characters in length appear
// as short changing arbitrary messages.

const dialogC = new QInputDialog(centralWidget);

dialogA.setLabelText('label A .............'); // 21 chars -----> works
dialogB.setLabelText('label B ..............'); // 22 chars -----> does not work
dialogC.setLabelText('label C .............'); // 21 chars -----> works

dialogA.setTextValue('input A .............'); // 21 chars -----> works

dialogC.setTextValue('input C ..............'); // 22 chars -----> does not work

dialogA.exec();
dialogB.exec();
dialogC.exec();

terminal commands:

npm install
npm run build
npm run dev

When the above commands are run, the visible app shows correct output for some but not all of the QInputDialog widgets.

Expected behavior

All of the QInputDialog widget labels and default responses should show as plain text.

Screenshots

correct display in QMessageBox widget even with longer string:

correct display in QInputDialog widget with labels and default responses that are 21 characters long:

incorrect display in QInputDialog widget of label that is 22 characters long; note that multiple runs of the identical code produce different apparently arbitrary incorrect labels, including blank labels on occasion, as shown:

incorrect display in QInputDialog widget of default response that is 22 characters long; note that multiple runs of the identical code produce different apparently arbitrary incorrect default responses (only a single screen shot is shown, but the difference between otherwise identical runs is comparable to the differences shown in the screen shots for labels above):
