Qt error Invalid use of incomplete type 'class UI::FrameLess'
0
I keep getting this error and I don't know why. It just says incomplete type of my class FrameLess. I don't think im missing including any files. I also want to specify that I have a mainwindow besides this widget and im trying to implement a UI form for my class FrameLess. Any help would be great. Thanks!

I keep getting this error and I don't know why. It just says incomplete type of my class FrameLess. I don't think im missing including any files. I also want to specify that I have a mainwindow besides this widget and im trying to implement a UI form for my class FrameLess. Any help would be great. Thanks!

I keep getting this error and I don't know why. It just says incomplete type of my class FrameLess. I don't think im missing including any files. I also want to specify that I have a mainwindow besides this widget and im trying to implement a UI form for my class FrameLess. Any help would be great. Thanks!

I keep getting this error and I don't know why. It just says incomplete type of my class FrameLess. I don't think im missing including any files. I also want to specify that I have a mainwindow besides this widget and im trying to implement a UI form for my class FrameLess. Any help would be great. Thanks!

I tried this by recreating a simple project and copying in your code, making it a "Qt Designer Form Class" (which I think you also did), and recreated the same error as you did.
But, looking at the code sample, this is not really intended to be a QDialog but rather a QObject, i.e. a class deriving from the main Qt base class (QObject). So it should not be used that way.
I looked at the code and saw these lines in the constructor:
FrameLess::FrameLess(QWidget *target) :_target(target),_cursorchanged(false),_leftButtonPressed(false),_borderWidth(5),_dragPos(QPoint()), ui(new Ui::FrameLess)
{
// ui->setup(this);
_target->setMouseTracking(true);
_target->setWindowFlags(Qt::FramelessWindowHint);
_target->setAttribute(Qt::WA_Hover);
_target->installEventFilter(this);
_rubberband = new QRubberBand(QRubberBand::Rectangle);
}
As can be seen, this class takes in a target widget and modifies this widget, making it frameless (by e.g. setting the according window flags, attributes etc.). So the proper use case would be something like this, in the class where you want it to be used:
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
new FrameLess(this);
}
The constructor call (new Frameless(this)) will modify the object that you pass to it in this way.
So, to get your example working, either recreate it in Qt Creator as a plain QObject-derived class, or to just do a quick test, remove from this part of the constructor:
FrameLess::FrameLess(QWidget *target) :_target(target),_cursorchanged(false),_leftButtonPressed(false),_borderWidth(5),_dragPos(QPoint()), ui(new Ui::FrameLess)
...the , ui(new Ui::FrameLess) part there at the end. I.e. don't assign anything to the ui class member.
In the .h file, remove this part:
private:
QWidget *_target = nullptr;
QRubberBand *_rubberband = nullptr;
bool _cursorchanged;
bool _leftButtonPressed;
Edges _mousePress = Edge::None;
Edges _mouseMove = Edge::None;
int _borderWidth;
Ui::FrameLess *ui; // <- remove this
QPoint _dragPos;
bool _dragStart = false;
By doing these changes, I could get your example working, but it's probably best to recreate it/delete the frameless.ui dialog from your project - it isn't used anyway, so it's best to just remove it.
Hope this helps! :-)

Thank you ! But I need the frameless.ui so that i can edit the user interface. I want a resizeable transparent frameless window, with a .ui file so i can add buttons and stuff to it.
– Blazur
Nov 17 '18 at 20:21
Yes. Please re-read my answer. You create the window with the.uifile and all that, then from the constructor in your window class, callnew FrameLess(this)- theFrameLessclass will then adjust your window class instance so that it's frameless. You could perhaps also merge the content from theFrameLessclass into your UI class (like you tried), but it might require more changes so I suggest going with this approach at first.

Yes. Please re-read my answer. You create the window with the.uifile and all that, then from the constructor in your window class, callnew FrameLess(this)- theFrameLessclass will then adjust your window class instance so that it's frameless. You could perhaps also merge the content from theFrameLessclass into your UI class (like you tried), but it might require more changes so I suggest going with this approach at first.

I tried this by recreating a simple project and copying in your code, making it a "Qt Designer Form Class" (which I think you also did), and recreated the same error as you did.
But, looking at the code sample, this is not really intended to be a QDialog but rather a QObject, i.e. a class deriving from the main Qt base class (QObject). So it should not be used that way.
I looked at the code and saw these lines in the constructor:
FrameLess::FrameLess(QWidget *target) :_target(target),_cursorchanged(false),_leftButtonPressed(false),_borderWidth(5),_dragPos(QPoint()), ui(new Ui::FrameLess)
{
// ui->setup(this);
_target->setMouseTracking(true);
_target->setWindowFlags(Qt::FramelessWindowHint);
_target->setAttribute(Qt::WA_Hover);
_target->installEventFilter(this);
_rubberband = new QRubberBand(QRubberBand::Rectangle);
}
As can be seen, this class takes in a target widget and modifies this widget, making it frameless (by e.g. setting the according window flags, attributes etc.). So the proper use case would be something like this, in the class where you want it to be used:
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
new FrameLess(this);
}
The constructor call (new Frameless(this)) will modify the object that you pass to it in this way.
So, to get your example working, either recreate it in Qt Creator as a plain QObject-derived class, or to just do a quick test, remove from this part of the constructor:
FrameLess::FrameLess(QWidget *target) :_target(target),_cursorchanged(false),_leftButtonPressed(false),_borderWidth(5),_dragPos(QPoint()), ui(new Ui::FrameLess)
...the , ui(new Ui::FrameLess) part there at the end. I.e. don't assign anything to the ui class member.
In the .h file, remove this part:
private:
QWidget *_target = nullptr;
QRubberBand *_rubberband = nullptr;
bool _cursorchanged;
bool _leftButtonPressed;
Edges _mousePress = Edge::None;
Edges _mouseMove = Edge::None;
int _borderWidth;
Ui::FrameLess *ui; // <- remove this
QPoint _dragPos;
bool _dragStart = false;
By doing these changes, I could get your example working, but it's probably best to recreate it/delete the frameless.ui dialog from your project - it isn't used anyway, so it's best to just remove it.
Hope this helps! :-)

Thank you ! But I need the frameless.ui so that i can edit the user interface. I want a resizeable transparent frameless window, with a .ui file so i can add buttons and stuff to it.

The error is: "Invalid use of incomplete type 'class UI::FrameLess' "
