Problem of Focus QMacNativeWidget

[skuallpa]

Hello everybody,

I am facing a problem with the use of QMacNativeWidget. Based on the example of code from the documentation of theQMacNativeWidget, I have simply tried to put a QTextEdit on a mac window. However, I cannot get the focus on the QTextEdit.

#include <QtGui/QtGui>
#include <QtGui/qmacnativewidget_mac.h>
#import <Cocoa/Cocoa.h>
 
int main(int argc, char **argv)
{
    QApplication app(argc, argv);
 
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    NSWindow *window = [[NSWindow alloc] initWithContentRect:NSMakeRect(200, app.desktop()->height() - 200, 239, 200)
                        styleMask:NSTitledWindowMask | NSClosableWindowMask
                                  | NSMiniaturizableWindowMask | NSResizableWindowMask
                        backing:NSBackingStoreBuffered defer:NO];
 
    QMacNativeWidget *nativeWidget = new QMacNativeWidget();
    nativeWidget->move(0, 0);
    nativeWidget->setPalette(QPalette(Qt::red));
    nativeWidget->setAutoFillBackground(true);
    QVBoxLayout *layout = new QVBoxLayout();
	QTextEdit *txtEdit = new QTextEdit("An Embedded Qt Button!", nativeWidget);
    txtEdit->setAttribute(Qt::WA_LayoutUsesWidgetRect); // Don't use the layout rect calculated from QMacStyle.
	layout->addWidget(txtEdit);
    nativeWidget->setLayout(layout);
 
    // Adjust Cocoa layouts
    NSView *nativeWidgetView = reinterpret_cast<NSView *>(nativeWidget->winId());
    NSView *contentView = [window contentView];
    [contentView setAutoresizesSubviews:YES];
    [nativeWidgetView setAutoresizingMask:NSViewWidthSizable | NSViewHeightSizable];
    [nativeWidgetView setAutoresizesSubviews:YES];
    NSView *txtEditView = reinterpret_cast<NSView *>(txtEdit->winId());
    [txtEditView setAutoresizingMask:NSViewWidthSizable];
 
    // Add the nativeWidget to the window.
    [contentView addSubview:nativeWidgetView positioned:NSWindowAbove relativeTo:nil];
    nativeWidget->show();
    txtEdit->show();
 
    // Show the window.
    [window makeKeyAndOrderFront:window];
    [pool release];
 
    return app.exec(); // gives us the same behavior in both
}

#include <QtGui/QtGui>
#include <QtGui/qmacnativewidget_mac.h>
#import <Cocoa/Cocoa.h>

int main(int argc, char **argv)
{
    QApplication app(argc, argv);

    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    NSWindow *window = [[NSWindow alloc] initWithContentRect:NSMakeRect(200, app.desktop()->height() - 200, 239, 200)
                        styleMask:NSTitledWindowMask | NSClosableWindowMask
                                  | NSMiniaturizableWindowMask | NSResizableWindowMask
                        backing:NSBackingStoreBuffered defer:NO];

    QMacNativeWidget *nativeWidget = new QMacNativeWidget();
    nativeWidget->move(0, 0);
    nativeWidget->setPalette(QPalette(Qt::red));
    nativeWidget->setAutoFillBackground(true);
    QVBoxLayout *layout = new QVBoxLayout();
	QTextEdit *txtEdit = new QTextEdit("An Embedded Qt Button!", nativeWidget);
    txtEdit->setAttribute(Qt::WA_LayoutUsesWidgetRect); // Don't use the layout rect calculated from QMacStyle.
	layout->addWidget(txtEdit);
    nativeWidget->setLayout(layout);

    // Adjust Cocoa layouts
    NSView *nativeWidgetView = reinterpret_cast<NSView *>(nativeWidget->winId());
    NSView *contentView = [window contentView];
    [contentView setAutoresizesSubviews:YES];
    [nativeWidgetView setAutoresizingMask:NSViewWidthSizable | NSViewHeightSizable];
    [nativeWidgetView setAutoresizesSubviews:YES];
    NSView *txtEditView = reinterpret_cast<NSView *>(txtEdit->winId());
    [txtEditView setAutoresizingMask:NSViewWidthSizable];

    // Add the nativeWidget to the window.
    [contentView addSubview:nativeWidgetView positioned:NSWindowAbove relativeTo:nil];
    nativeWidget->show();
    txtEdit->show();

    // Show the window.
    [window makeKeyAndOrderFront:window];
    [pool release];

    return app.exec(); // gives us the same behavior in both
}

To copy to clipboard, switch view to plain text mode 

This is the result, I cannot edit nor select the text (it stays gray).



Anyone has an idea why this happen?. I cannot find more documentation and example about QMacNativeWidget.
Thanks in advance for any help.

Hello,

I've found a solution:
Add

QApplication::setAttribute(Qt::AA_MacPluginApplication);

QApplication::setAttribute(Qt::AA_MacPluginApplication);

To copy to clipboard, switch view to plain text mode 

before

QApplication app(argc, argv);

QApplication app(argc, argv);

To copy to clipboard, switch view to plain text mode 

It seems to work.
