[SOLVED] resizable windows (how to)

MacOSX and iOS
1

I am trying to add the ability to resize my os x application, as well as remove the full-screen button.   Every since I added the setFullScreen() and setResizable() calls in my MainWindow constructor, the application triggers a jassert() in juce_ResizableWindow.cpp

 

class MainWindow    : public DocumentWindow

    {

    public:

        MainWindow (String name)  : DocumentWindow (name,

                                                    Colours::lightgrey,

                                                    DocumentWindow::allButtons)

        {

            setUsingNativeTitleBar (true);

            MainContentComponent* mcc = new MainContentComponent();

            centreWithSize (getWidth(), getHeight());

            setContentOwned (mcc, true);

            

            

            this->setFullScreen(false);

            

            this->setResizable(true, true);

            int maxHeight = Desktop::getInstance().getDisplays().getMainDisplay().userArea.getHeight();

            this->setResizeLimits(1024, 512,

                                  1310,

                                  maxHeight );

            setVisible (true);

            

           // mcc->setMainWindow(this);

            

            

        }

What am I doing wrong?   it seems the setContentOwned() is where everything goes downhill and causes the problems.

Just checked your code on OSX Yosemite and didn't get any asserts... 

(created a new GUI application in Introjucer and just copypasted your code into the MainWindow constructor)

What assert are you hitting exactly, and are you sure it's not caused by something else?

The jassert's here are getting caught: 

 

void ResizableWindow::childBoundsChanged (Component* child)

{

    if ((child == contentComponent) && (child != nullptr) && resizeToFitContent)

    {

        // not going to look very good if this component has a zero size..

        jassert (child->getWidth() > 0);

        jassert (child->getHeight() > 0);


        const BorderSize<int> borders (getContentComponentBorder());


        setSize (child->getWidth() + borders.getLeftAndRight(),

                 child->getHeight() + borders.getTopAndBottom());

    }

}

edit:  

looks like I had setSize() in my MainContentComponent commented out!!!  arghh!!!!  problem solved.

One thing I particularly like about JUCE is that usually, the asserts are telling you pretty exactly what went wrong :-)
