@kain Yes, I think I have understand what you want to achieve. It ist not so easy.
I seen one possibility which is not too difficult.
You create a kind of template class to register the dialog message and store the result.
Something like this:
class DialogRequest : public QOject
{
Q_OBJECT
Q_PROPERTY(QString message READ message CONSTANT)
public:
explicit DialogRequest(const QString& message, Object *parent = 0): QObject(parent), m_message(message) {}
QString message() const { return m_message; }
signals:
void done(QObject* dialog, int result);
private:
QString m_message;
}
class DialogInterface : public QOject
{
Q_OBJECT
public:
explicit DialogInterface (Object *parent = 0): QObject(parent) {}
DialogRequest * createMessage(const QString& message)
{
// add parent to avoid QML taking ownership of instance!!!
return new DialogRequest(message, this);
}
void showDialog(DialogRequest * dlg) { emit requestDialog(dlg); }
signals:
void requestDialog(QObject* dialogObj);
}
Create new QML Component called, for example MyDialog:
Dialog {
id: dialog
property var dialogInfo
title: !!dialogInfo ? dialogInfo.message : "Title"
modal: true
width: 200
standardButtons: Dialog.Ok | Dialog.Cancel
onOk: {
console.log("OK pressed")
dialogInfo .done(dialogInfo , 0);
}
onDiscard: {
console.log("Cancel pressed")
dialogInfo.done(dialogInfo , -1);
}
}
change QML as follow:
Item {
id: window
visible: true
width: 640
height: 480
Connections {
target: dialogInterface
onRequestDialog: {
var newDialog = Qt.createQmlObject("MyDialog.qml", window, "dynamicMessage")
newDialog.dialogInfo = dialogObj
newDialog.open()
}
}
}
Then in C++ something like this
auto* newDialog = dialogInterface.createMessage("This is a title");
connect(newDialog, &DialogRequest::done, this, [&](QObject* dialog, int result){
dialog->deleteLater();
if(result == 0)
{
// do Ok stuff
}
else
{
// do error stuff
}
});
dialogInterface.requestDialog(newDialog);
This is just an example in which way it can be done, and must be fine tune/adapted.
Just to give you a starting impulse
Hope this will help you to solve your problem.
