    QMainWindow(parent),
    ui(new Ui::Editor)
{
    ui->setupUi(this);

    QString ProjectLocation = "C:";
    filemodel = new QFileSystemModel(this);
    filemodel->setRootPath(ProjectLocation);

    ui->fileExplorer->setModel(filemodel);
}

Editor::~Editor()
{
    delete ui;
}

void Editor::on_actionAddNew_triggered()
{
    AddNew *addnew = new AddNew;
    addnew->show();
}

void Editor::on_actionDocumentation_triggered()
{
    QString link="https://bare-docs.github.io/";
    QDesktopServices::openUrl(QUrl(link));
}

void Editor::on_actionNew_triggered()
{
    AddNew *addnew = new AddNew;
    addnew->show();
}

void Editor::on_actionOpen_triggered()
{
    QString filename = QFileDialog::getOpenFileName(this, "Choose a file" );
    QFile file(filename);
    currentFile = filename;
    if(!file.open(QIODevice::ReadOnly | QFile::Text)){
        QMessageBox::warning(this, "Error", "Unable to Open File: " + file.errorString());
    }
    QTextStream in(&file);
    QString text = in.readAll();
    ui->codingarea->setPlainText(text);
    ui->itemname->setText(filename);
    file.close();
}

Restore from what?
Please explain better what you are doing.

ELEMENTICY

@jsulm i cant click the restore button,
alt text
the middle button,between the "_" and "X" button.

jsulm

@ELEMENTICY It's not "restoring", it's resizing. Do you set fixed size for your application window?

ELEMENTICY

@jsulm No i didt

SGaist

Hi,

Did you tweak any flags in designer with regards to these buttons ?

How did you maximize your window in the first place?

@jsulm said in Unable to restore my Application:

@ELEMENTICY It's not "restoring", it's resizing.

To be fair, that's Windows terminology. If you hover your mouse cursor over the button between "Minimize" and "Close", the tooltip says either "Maximize" or "Restore Down"

@ELEMENTICY
If you're not sure how this came about. Start with a 10-line program which just creates a top-level QWidget or QMainWindow. Make sure that does allow "Restore". Then put in what you might have in your real app, like any flags you put on the window.

Thank You

Are you sure it is not QDialog?? If it is Qdialog then it will show like this.
Just see your UI file

ELEMENTICY

@Thank-You its mainwindows

@ELEMENTICY said in Unable to restore my Application:

its mainwindow

Then you must have changed something. QMainWindow is resizable, minimizable and restorable by defaut.
Do what @JonB suggested. Create a new, empty project and open the MainWindow.

What kind of window do we see in your screenshot? Are you sure, that it is your MainWindow? Because you create some QDialogs and QMessageBoxes here:

@ELEMENTICY said in Unable to restore my Application:

void Editor::on_actionNew_triggered()
{
AddNew *addnew = new AddNew;
addnew->show();
}

and here:

@ELEMENTICY said in Unable to restore my Application:

void Editor::on_actionOpen_triggered()
{
QString filename = QFileDialog::getOpenFileName(this, "Choose a file" );
QFile file(filename);
currentFile = filename;
if(!file.open(QIODevice::ReadOnly | QFile::Text)){
QMessageBox::warning(this, "Error", "Unable to Open File: " + file.errorString());
}
QTextStream in(&file);
QString text = in.readAll();
ui->codingarea->setPlainText(text);
ui->itemname->setText(filename);
file.close();
}

You don't show us the titlebar of your AddNew dialog(?) or your QFileDialog, don't you? :-)

ELEMENTICY

@Pl45m4 im sure its mainwindows.And these
void Editor::on_action......

is the trigger button on menu.
which just open up new window only.And the current one is 100% MainWindow

ELEMENTICY

@JKSH

QApplication a(argc, argv);
    Editor w;
    w.setWindowState(Qt::WindowMaximized);
    w.show();

JKSH

@ELEMENTICY said in Unable to restore my Application:

    w.setWindowState(Qt::WindowMaximized);

What happens if you remove this line?

ELEMENTICY

@JKSH still cant restore,just when start,its not fullscreen mode.

J.Hilk

@ELEMENTICY
and

QApplication a(argc, argv);
    QWidget w;
    w.resize(50,50);
    w.setWindowState(Qt::WindowMaximized);
    w.show();

behaves the same? what OS and window manager do you use?

ELEMENTICY

@J-Hilk windows 10

ELEMENTICY

@J-Hilk and yea it doesnt work.Also its MainWindow Why dont you trust me xD

Pl45m4

@ELEMENTICY

Because it's nearly impossible that you can't resize your window, when you didn't change anything. There must be some settings that got changed.

Have you tried to create an empty project and resize / restore the MainWindow there? Does it work?
Have you checked your design file? Have you made changes there?
