GUI Disappearing #1522

Since upgrading I've been having an issue where the GUI disappears completely.

For example, I'll be using Bitcoin-Qt, then exit it using the red cross. If I then click on Bitcoin in the dock, the GUI no longer shows up. It has definitely been selected though, because the task bar changes to Bitcoin and shows Bitcoin options.

Anyone else been having a similar problem?

Needs more information; Upgrading from what version to what version? Which OS? Do you have "close to tray" enabled? Isn't it simply shutting down?

Sorry, didn't copy the top half of my issue. OS X 10.7.4, upgrading from 0.6.2.2 to 0.6.3

Close to tray?

Never mind, that option doesn't exist on MacOSX.

A problem with the dock icon on OSX has been solved something like a month ago:

https://github.com/bitcoin/bitcoin/commit/b06f9c1364ab70763ded9c0c7ba795c0da72aa7a

I'm not sure whether it is backported to 0.6.x, though.

I've had a look into this, and adding that code back in actually fixes the problem.

But that brings back the problems in #1327 right? We really need someone to hack on bitcoin ui on the mac, currently it's mostly guess work.

Same problem here. i have to right-click at dock icon and select "Show/Hide Bitcoin" to bring the window back.

Can anyone answer my question? Does re-adding that code bring back issue #1327?

I have a feeling it does. Although that would probably be preferred over the gui dissapearing completely. Not all users would realise that they have to use show/hide to bring it back. Whereas they will more than likely click the dock icon more than once if the gui shows up and then dissapears.

I have this same problem on a linux box. Commenting out the #ifndef Q_OS_MAC in BitcoinGUI::createTrayIcon (and relative #endif) fixes the issue for me, which suggests that macro is defined when it should not be...

Forget it, it still works after dropping the comments. There must be an issue with the dependency tracker which prevented my build to catch a recent fix

Any Mac dev, who can contribute here?

Has this been fixed?

Works for me on OSX 10.8 using git HEAD. Please open a new issue if it doesn't work for you when 0.8 is out.

With the new version 0.8 the GUI disappears completely again. I have to restart bitcoin-qt to bring it back. OSX 10.8.2 on three different computers. Others on the forum reported the same issue: https://bitcointalk.org/index.php?topic=145184.msg1582293#msg1582293

I have observed this in OS X 10.7.5 as well, but to clarify: the window is irretrievable only after I hit the window-close button. If I hit the window-minimize button, the window minimizes as expected and can be restored in the usual way.

Does this have to do with tray icon at all ? Do you have a tray icon ?

The closest equivalent to a system tray in Mac OS is the right-hand side of the menu bar. My Bitcoin-Qt does not put an icon in the menu bar.

I played with the window options "Minimize to the tray instead of the taskbar" and "Minimize on close" to see if they had any effect, but they do not. Moreover, these settings do not appear to be retained in the Mac OS version.

I found an older thread on the Qt Project forums that may or may not be relevant here: http://qt-project.org/forums/viewthread/2416

I can work on doing builds on my machine if you are still in need of people who can make and test their own builds on Mac OS.

RE: working on doing builds: yes, we need a Qt/OSX programmer. My main machine is OSX, but I spend most of my time working on lower-level code, not GUI stuff.

Okay. I was just able to run one of my own builds, so you can consider me at least a rookie QA engineer for Mac. :smile_cat:

Here would be one way to make a quickie fix. In BitcoinGUI::closeEvent is this block:

     if(clientModel)
     {
#ifndef Q_OS_MAC // Ignored on Mac
         if(!clientModel->getOptionsModel()->getMinimizeToTray() &&
            !clientModel->getOptionsModel()->getMinimizeOnClose())
         {
             qApp->quit();
         }
#endif
     }

Moving the #endif up by 3 lines would at least ensure that the app quits when the window-close button is clicked.

However, I think I see some possibilities for enabling minimize-to-tray and minimize-on-close on Mac OS, so I'm going to play with those some more.

if I change

void BitcoinGUI::createTrayIcon()
{
#ifndef Q_OS_MAC
trayIcon = new QSystemTrayIcon(this);

trayIcon->setToolTip(tr("Bitcoin client"));
trayIcon->setIcon(QIcon(":/icons/toolbar"));
trayIcon->show();
#endif

to

void BitcoinGUI::createTrayIcon()
{
trayIcon = new QSystemTrayIcon(this);
#ifndef Q_OS_MAC

trayIcon->setToolTip(tr("Bitcoin client"));
trayIcon->setIcon(QIcon(":/icons/toolbar"));
trayIcon->show();
#endif

the menu on the dockicon appears again.

For those watching at home, @Nerzahd moved #ifndef Q_OS_MAC down one line to keep trayIcon = new QSystemTrayIcon(this); from being excluded by the conditional.

(I had to diff the two to figure out what was going on.) :grin:

I'm not sure why that patch helps on Mac really ^^. Can some Mac-capable dev enlighten me?

You have a point. At least this way the call the call to QSystemTrayIcon will get compiled into the Mac version, but without the call to trayIcon->show, it may be useless. I have a Mac and can try this out (just not right this moment).

Wait, were you talking about @Nerzahd's patch or mine?

i'm not a developer but i think it has something to do with:

// Create system tray menu (or setup the dock menu) that late to prevent users from calling actions,
// while the client has not yet fully loaded
if(trayIcon)
    createTrayIconMenu();

createTrayIconMenu() on Mac should work without depending on trayIcon to be non-zero. Perhaps that is the problem why it works, when allowing trayIcon = new QSystemTrayIcon(this); on Mac.

Solution could be to call createTrayIconMenu() on Mac always. Can a Mac dev try this?

Edit: I created a patch, dunno if it works though ^^.
