@davidjs1 Yeah May be it will work, try this example

@JoeCFD Thank you for your answer, but that was exactly what I had done - tried and tried all over again. The solution came now with vigorously erasing all of AndroidSDK, upgrading Creator. Now it works!! I'll probably never know why it didn't before. :-)

Hi, I'm still using Qt5 but I think Qt6 is the same.
I think it is non necessary to use java to read and write file or to relose an uri.
I think the Qt classes are enought.
I'm not so expert on Android. You can ask here

As an IT administrator, I value the granular control that Apptec360 MDM offers. From setting restrictions on device functionalities to configuring security settings, I have full control over device management. The reporting and analytics dashboard provides valuable insights that help me track device usage and compliance.

I suggest deleting this thread

@shokarta try with Android FileDialog

FileDialog { title: qsTr("Select a File") fileMode: FileDialog.OpenFile onAccepted: { if(selectedFiles.length) { console.log("we selected: ", selectedFiles[0])

Selected File 'München.pdf' from FileDialog
...this gives you per ex:

content://com.android.providers.downloads.documents/document/32

// you can check from C++ and verify fileUrl:

QFileInfo fileInfo(fileUrl); qDebug() << "verifying fileUrl: " << fileUrl; qDebug() << "BASE: " << fileInfo.baseName(); qDebug() << "FileName: " << fileInfo.fileName(); qDebug() << "Path: " << fileInfo.path(); qDebug() << "absoluteFilePath: " << fileInfo.absoluteFilePath(); return fileInfo.exists();

this gives you:

verifying fileUrl: "content://com.android.providers.downloads.documents/document/32" BASE: "München" FileName: "München.pdf" Path: "content://com.android.providers.downloads.documents/document" absoluteFilePath: "content://com.android.providers.downloads.documents/document/32" file exists

You can use Qt in Java (so also in Kotlin) using QtJambi.

I made the application Mouse Melon with Kotlin and Qt.

@cristian-adam Thank you very much

I found that the scribble project in the widjets example directory controls a mouse event to draw a line or image.
So I think that I create the signature capture function by using it.

Thanks

Looks like the fixed this issue with a partial revert for Qt 6.8+ See: https://codereview.qt-project.org/c/qt/qtbase/+/566570

Wish they'd back port to 6.7, but I understand...

Have you checked the 5.15 documentation?

Hello, has your problem been resolved? I have also encountered this situation and would like to ask you how to handle it

I have added the library path, "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/tslib/lib"
So the project, fingerpaint is working.

Thanks JonB.

And

MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) , ui(new Ui::MainWindow) { ui->setupUi(this); m_form = new Dialog; m_form->hide(); m_form->setParent(ui->widget_2); } MainWindow::~MainWindow() { delete ui; } void MainWindow::on_pushButton_clicked() { m_form->show(); } void MainWindow::on_pushButton_2_clicked() { m_form->hide(); }

As shown in the figure, "widget_1" is on the left and "widget_2" is on the right, "dialog.ui" is all filled with pink
