Combining widgets

[TETTRA]

@VRonin Excuse me but I didn'i understand a bit. Can you give me some example?

[VRonin]

Something like:

class ExampleWid : QMainWindow{
Q_OBJECT
Q_DISABLE_COPY(ExampleWid)
public:
explicit ExampleWid(QWidget* parent = Q_NULLPTR)
:QMainWindow(parent)
{
m_centralWid=new QMainWindow(this);
m_centralWid->setWindowFlags(Qt::Widget);
setCentralWidget(m_centralWid);
}
public slots:
void spawnWidget(){
auto tempLabel = new QLabel("exaple");
auto tempDock = new QDockWidget("example dock");
tempDock.setWidget(tempLabel);
m_centralWid->addDockWidget(Qt::NoDockWidgetArea,tempDock);
}
private:
QMainWindow* m_centralWid;
};

call spawnWidget to create new windows

Edit

addDockWidget shold be called from the central widget

@VRonin It's not what it takes. Sorry

@TETTRA
Hi
You really have to explain a bit better what you want. :)

I do use photoshop cc 2014 and i have no idea what you mean.

You mean tear off windows, ( from a tab ) to a floating window and then be able to drag back again to a tab ?

[TETTRA]

@mrjj Exactly this!!!!!

[mrjj]

@TETTRA
Ok. Then @VRonin code is the way to go.
Its not directly supported by the Docks. (to dock in center)
They will only docks to the sides. ( and only dock in mainwindows)
But it is possible to cheat and and use an extra mainwindow and use that for the central docking so
one can get that effect. But it takes some tweaking and fiddling to get it to work.

[TETTRA]

Can you tell me how to do this? Give some kind of example, pls

[mrjj]

@TETTRA
There is no premade , just to use solution. ( that i have seen)
The code @VRonin provide is a good starting point.

You should read about QDockWidget and how it works. Then
try to make it.

http://doc.qt.io/qt-5/qdockwidget.html
this one also cover it.

If you are brand new to Qt, it's not a good start project as such as it will take
some fiddling to feel like photoshop.

[TETTRA]

@mrjj You right. How can I designate the correct answer? And yet, how to do it, if I have everything in different files?(From projectWindow, I want to make a QDockWidget. Is it possible?) ! sorry for this bad picture

[mrjj]

• I want to make a QDockWidget. Is it possible?

You mean you want to include the widgets from other files?

Ys, just include the .h from the other widgets into the Dock one and
then you can create those from code. ( and insert into Dock)

[TETTRA]

@mrjj Sorry, but I'm new, could you give me an example?

[mrjj]

@TETTRA
Example on ?

[TETTRA]

@mrjj Yes

[mrjj]

@TETTRA
sorry ?
you just include the .h file and then u can use the class

//somefile.cpp
#include "mywidget.h"
then you can do
mywidget * w= new mywidget();

[TETTRA]

@mrjj It doesn't work out for me.

DockWidget:

#include "dockwodgets.h"
#include "stylehelper.h"

dockWodgets::dockWodgets()
{
    layer = new QDockWidget();
}

Connect:

//docks
             docks = new dockWodgets();

[mrjj]

@TETTRA
you must give more details.
what is error ?
what does not work ?
I cant tell anything from that code :)
seems fine.

[TETTRA]

@mrjj
DockWidget

#include "dockwodgets.h"
#include "stylehelper.h"

dockWodgets::dockWodgets()
{
    layer = new QDockWidget();
}

MainWindow

  //docks
             docks = new dockWodgets();

That's all I did. My program is running, but the "docks" isn,t shown.

[mrjj]

@TETTRA
make sure to show() on it.
layer = new QDockWidget();
layer->show();

[TETTRA]

@mrjj This widget simply opens. I need him open already and attached to the main window.

[mrjj]

@TETTRA
You also need to add it to the mainwindow with
