Problems resizing openGl component.(follow-up on old thread)

General JUCE discussion
#1

Hi,

A long time ago I posted a question which I still haven’t had solved here is a follow-up. When I resize my window the openGl canvas does not resize accordingly.

I get this error when at run-time:

I believe I do the resizing similarly to how it’s done in the juceDemo.exe

[code]class VstAnalyzerWindow : public DocumentWindow
{
OpenGlCanvas* openGlCanvas1;
OpenGlCanvas* openGlCanvas2;

public:
//==============================================================================
VstAnalyzerWindow()
: DocumentWindow (T(“VstAnalyzer”),
Colours::lightgrey,
DocumentWindow::allButtons,
true)
{
setContentComponent (new VstAnalyzer());

	setVisible (true);
	centreWithSize (800, 512);
	this->setResizable(true,true);
	this->setResizeLimits(512,512,2048,2048);

	// adding buttons
	TextButton* buttons[NUMBER_OF_BUTTONS];
	for(int i=0;i<NUMBER_OF_BUTTONS;i++)
	{
		buttons[i] = new TextButton(T("Button"+String(i)));
		addAndMakeVisible(buttons[i]);
		buttons[i]->setBounds(10,30*i+50,50,20);
	}

	buttons[NUMBER_OF_BUTTONS-1]->setButtonText(T("EXIT!"));
	buttons[NUMBER_OF_BUTTONS-1]->changeWidthToFitText();

	// adding Opengl canvas
	openGlCanvas1 = new OpenGlCanvas();
	openGlCanvas2 = new OpenGlCanvas();
	addAndMakeVisible(openGlCanvas1);
	//addAndMakeVisible(openGlCanvas2);
	openGlCanvas1->setBounds( 100, 100, this->getWidth()-120 , this->getHeight()-120);
	//openGlCanvas2->setBounds( 100, 100, 100,100);//this->getWidth()/2-120 , this->getHeight()/2-120);
}

void resized()
{
	openGlCanvas1->setBounds (100, 100, getWidth()-120, getHeight()-120);
}

…[/code]

can someone please tell me what I’m missing here?

thanks

I can instantly see what you’ve done wrong, but am surprised that you’re asking about it here without actually trying to debug it?? A quick look at the stack trace when it crashes would have shown you exactly what’s happening!
