Confirmed #2: Attaching rasterpos-fix-before-and-after-screenshot.jpg showing the problem/solution, and agree with the suggested fix to Fl_Gl_Window::make_current(). Since finding the window offset is now needed in at least two places in the code, will probably add a method to the Fl_Window base class that returns x/y offsets, and use that to implement the fix.

Re: [fltk.development] fltk and high res retina display?
I just upgraded to a newer mac laptop, and discovered that fltk apps don't render in the new highres mode. It seems like it shouldn't be too hard for text at least, but I wasn't able to find an enable high res flag after a bit of looking at https://developer.apple.com/library/mac/#documentation/GraphicsAnimation/Conceptual/HighResolutionOSX/Introduction/Introduction.html#//apple_ref/doc/uid/TP40012302-CH1-SW1 There is kWindowHighResolutionCapableAttribute but it's for Carbon. The implication seems to be that for Cocoa apps it should just work. Any of the more mac knowledgeable sorts know what's going on here, or should I keep poking through the apple docs? I have activated QuartzDebug, as suggested in the above-mentionned web-page, to test high resolution without a retina display, and discover that fltk graphics have jagged look everywhere. What a delusion! A very strange thing is that system-created windows (the About my prog, open/save and print dialogs) also have jagged graphics. This suggests we miss some application-wide property. ___ fltk-dev mailing list fltk-dev@easysw.com http://lists.easysw.com/mailman/listinfo/fltk-dev

I have activated QuartzDebug, as suggested in the above-mentionned web-page, to test high resolution without a retina display, and discover that fltk graphics have jagged look everywhere. What a delusion! A very strange thing is that system-created windows (the About my prog, open/save and print dialogs) also have jagged graphics. This suggests we miss some application-wide property. Adding keyNSHighResolutionCapable/keytrue/ in the app's Info.plist makes standard FLTK widgets/fonts draw fairly well (there are some small artifacts and off-by-one line drawings here and there, but nothing major). OpenGL windows are still drawn at half-resolution, though...

Re: [fltk.development] fltk and high res retina display?
I just upgraded to a newer mac laptop, and discovered that fltk apps don't render in the new highres mode. It seems like it shouldn't be too hard for text at least, but I wasn't able to find an enable high res flag after a bit of looking at https://developer.apple.com/library/mac/#documentation/GraphicsAnimation/Conceptual/HighResolutionOSX/Introduction/Introduction.html#//apple_ref/doc/uid/TP40012302-CH1-SW1 OK. As reported before by Christophe, the solution is to add one item to the application's Info.plist file, as explained by Apple there: http://developer.apple.com/library/mac/#documentation/GraphicsAnimation/Conceptual/HighResolutionOSX/Explained/Explained.html The item is of the Boolean type, is named NSHighResolutionCapable, and should be turned on. The effect is that when File/Get Info from the finder is done on the application, the Open in Low Resolution option becomes activated and unchecked, instead of greyed out and checked. ___ fltk-dev mailing list fltk-dev@easysw.com http://lists.easysw.com/mailman/listinfo/fltk-dev

[fltk.general] Caps Lock detection
I need to immediately detect when Caps Lock is turned on or off in our
login screen, so I can alert the user. Neither of the approaches I've
tried works.
Both the overrides of Fl_Window::handle and Fl_Secret_Input::handle
don't report that Caps Lock has been turned off until the message after
it's been turned off.
Here's the below sample program's output for the transition from Caps
Lock on to off.
caps lock 7
caps lock 6
caps lock 7
caps lock 8
caps lock 9
caps lock 8
caps lock 10

if (event== FL_SHORTCUT Fl::event_key()== 65509)
Without check of key every shortcut signals caps lock, thats wrong. And
it seems, the real state establishs after the events had run through,
but because of binary state it's no problem.

Re: [fltk.general] Caps Lock detection
Thanks for the quick reply. Here's what I have now. It's reporting the
opposite of of the Caps Lock state. In other words, (Fl::event_state()
FL_CAPS_LOCK) is zero when Caps Lock is on, and nonzero when it's off.
Is that what you meant in your last message?
I'm less than enthusiastic about displaying the 'Caps Lock is on'
message when the test in the code says it's off.
Is there really no alternative?
Thanks,
Howard Rubin

Well, there should be a better way, but it looks like you found a bug
or at least some inconsistency. I'll post two different modified test
programs (derived from yours) that do unfortunately show inconsistent
behavior on Windows and Linux on my test systems, i.e. Windows 7 and
Linux Ubuntu 12.04 an a Virtualbox VM. Maybe someone can test it on
a real Linux box and on Mac OS X ?
Howard, what's your environment ?
Here's #1 that shows more events and gives a clue how to handle the
key, and it works well on Windows, but doesn't on my Linux VM:
$ cat capslock.cxx

std::cout event = fl_eventnames[event] ... ;
if (Fl::event_state() FL_CAPS_LOCK)
std::cout WARNING: CAPS LOCK is set;
std::cout std::endl;
return 1;
}
if ((event == FL_SHORTCUT || event == FL_KEYDOWN || event ==
FL_KEYUP)
Fl::event_key() == FL_Caps_Lock) {
std::cout event = fl_eventnames[event] ... ;
static int n = 0;
if (Fl::event_state() FL_CAPS_LOCK) {
std::cout caps lock ++n std::endl;
} else {
std::cout caps unlock ++n std::endl
std::endl;
}
return 1;
} else
return Fl_Window::handle(event);
}
};
int main(int argc, char* argv[]) {
myWindow* win = new myWindow(300, 200, );
new Fl_Secret_Input(20, 20, 100, 20, );
new Fl_Button(20, 120, 100, 20, Test);
win-end();
win-show();
return Fl::run();
}

event = FL_KEYDOWN ... caps lock 9
event = FL_KEYUP ... caps lock 10
event = FL_KEYDOWN ... caps lock 11
event = FL_KEYUP ... caps unlock 12
You can see (or guess) that the CAPS LOCK state is updated *before*
the handle message is called on FL_KEYDOWN events, if CAPS LOCK is
being turned ON, but *after* the FL_KEYDOWN event, if it is turned
OFF. That's why the program shows the caps unlock message only on
FL_KEYDOWN events.
Obviously it's a little difficult to get the state of these toggle
keys in a platform independent way, and hence this doesn't seem to
work well on my Linux VM:

Re: [fltk.opengl] event_x() To Get FL_Gl_Window Coordinates
On 03.04.2013 22:54, Mike Werner wrote: I want to be able to left click in an OpenGL window and have the mouse coordinates in that window returned (i.e. relative to the upper left corner of the window). Seems like I should be able to do this using Fl::event_x. However it's turning out to be difficult. First of all the only way I can get event_x to return anything is to put it in the draw function of my Fl_Gl_Window with the syntax Fl::event_x(). But this doesn't return anything when I click in the OpenGL window. It ONLY returns coordinates when I click on a button outside the OGL window. And the X value returned is relative to main FLTK window. Not what I need. First of all: Fl::event_x() is only valid in the event handling code or in a callback called from this code. Putting Fl::event_x() in a draw() method can only give you _undefined_ values, i.e. it _can_ sometimes be what you expect. This is because Fl::event_x() uses a static variable that is updated only on some events like mouse clicks, but also on FL_MOVE and maybe others. I saw your follow-up: using a button underneath the OGL window might do what you need, since you get the button callback when the click event is handled. There is no way other than to do the coordinate translation yourself, since the OGL window has its own coordinate system, but the button coordinates are relative to the button's window(). Was hoping to be able to put event_x() in the draw function never put it in the draw() method, see above. or in the callback to Fl_Gl_Window and get OGL window relative coordinates. The only idea I have now is to put a large button underneath the OGL window. When I click inside the OGL window, this button will be activated and I'll get an x cord. relative to the main FLTK window and have to subtract off the upper left corner coordinates of the OGL window. Anyone have a more elegant solution? I'd try to put an invisible box or button in the OGL window that serves the same purpose as your button in the main window. The invisible box could be an own derived class, so that you can use the handle() method, but a simple callback would also do the job. However, event handling in GL Windows might differ from normal windows, so I don't know if this would work.
