@JNBarchan
It's great. I just use this function: QWidget::createWindowContainer. Maybe I can try to modify the code. Thank you for your reply.

Hi,

Do you mean you have two different executable started ?

@Sh1gs
Just as a note.
There is no difference adding widgets in code or adding via Designer.
The setupUI() as seen in mainwindow ctor creates the Designer widgets as code.

So the only true difference is handwritten versus generated from UI file.
Also adding via Designer, gives easier translations as the translate function is generated for the user.

@GTDev Thanks for the reply.
I will go on with V-Play and try to implement my app with V-Play for now. But if anybody has another idea why this happens I would be grateful for cheering.

You can set the sizePolicy of each element in a layout. Typically a button has a fixed vertical size and an expanding horizontal size (dont get confused with "minimum" and "expanding" size policy).
Maybe it is useful to take the Qt creator and create a simple application and play around with layouts...

I've found the problem it is a process deleted without initialized.

Hi,

You have an example in CMake's documentation here

How about the Fortune example?

Cheers.

@yuvaram
thanks a lot :)

You can call QWidget::resize() in main.cpp to make your viewer bigger.

Hello @applefier ,

To fix the size of your layout you can use

the setSizeConstraint ( SizeConstraint ) function

and you have to put QLayout::SetFixedSize as arg of SizeConstraint

Here is the doc explanation:

sizeConstraint : SizeConstraint

This property holds the resize mode of the layout.

enum QLayout::SizeConstraint

The possible values are:

Constant Value Description QLayout::SetDefaultConstraint 0 The main widget's minimum size is set to minimumSize(), unless the widget already has a minimum size. QLayout::SetFixedSize 3 The main widget's size is set to sizeHint(); it cannot be resized at all. QLayout::SetMinimumSize 2 The main widget's minimum size is set to minimumSize(); it cannot be smaller. QLayout::SetMaximumSize 4 The main widget's maximum size is set to maximumSize(); it cannot be larger. QLayout::SetMinAndMaxSize 5 The main widget's minimum size is set to minimumSize() and its maximum size is set to maximumSize(). QLayout::SetNoConstraint 1 The widget is not constrained.

Hope this will work,

Regards !

@mcosta Thank you it all finally working fine :)

The problem is solved,

The problem was caused by the difference between Qt SDK compiler and application compiler !

I recompiled the src of qt sdk with the compiler used to my program and now it work !
thanx,

Hi and welcome to devnet,

Do you have the idea of building a website using Qt ? Or do you want some backend code be run using Qt ?

as for web programming, QT is not the best bet, mate. It's a great tool for building cross-platform apps, like this. And it has a big potential on this for individual devs

I'm not sure anyone cares about this anymore, but I believe I know what the problem is.

When the plugin class is created, it is actually created outside the currently executing QApplication (via dlopen) and the code is running in a different thread. By reading up a bit on dlopen, it seems that the memory where the library is created comes from a different pool and that all libraries (used like this at least), should make sure to implement a function to destroy themselves.

Not sure if this makes any sense for someone, but it does for me.

Now, I just need to figure a way to get the libraries thread to join with the man QApplication that is already running.

@Ajith_P_V Yes that is right, you don't need to add the physical device. That was really just an extra option in case that was convenient to you later on : )

Have a look at creating kits for cross compiling in the qt docs if you can find it! - there are quite a few bits of info out there that may fill in the gaps I have left. I only gave the general steps required.

@Paul-H. D'oh! Why, of course, how silly of me. visibility: Window.AutomaticVisibility does NOT automatically do visible: true.

Truly a case of needing to ask someone else to realize you're making a rookie mistake. Thanks for your help, Paul.

This looks very promising, thanks ! :)

Hi,

Sure you can. One thing that you might use is a QProgressBar (with min and max at the same value so it's animated as in don't know how long it can take. Or you can use a gif in a QMovie object.

Good !

However, I'm not sure I'm following you on that one. Where did you put that resize ?

If you can't from the Topic Tools menu, then just edit the thread title and prepend [solved]

@Varius said:

thread = new QThread(this);
console->moveToThread(thread);

IIRC, these lines are doing more than you think they do. thread's parent is your object, then you move your MyObject instance to thread, so all objects who are child of your MyObject instance are moved the thread. So thread will be moved to itself.

All in all, you should rather have thread in your main as a stack object
