Modifier keys overriding keyPressed events [OSX, 0.10.0]

beginners
1

Hello, in 0.10 w. High Sierra I’m not registering two keypresses when a modifier key is also pressed. For example;

void ofApp::keyPressed( ofKeyEventArgs& e) {
    ofLog() << "ofApp::" << (e.key == 'a') << (ofGetKeyPressed(OF_KEY_COMMAND));
};

Log output is;

ofApp:: 0 1 // cmd is pressed
ofApp:: 0 1 // + a is pressed

Same for permutations

ofLog() << "ofApp::" << (ofGetKeyPressed('a')) << (ofGetKeyPressed(OF_KEY_COMMAND));
// etc

Though it works for two non-modifier keys…

you should try ofxModifierKeys https://github.com/satoruhiga/ofxModifierKeys
I’m not sure if is still works on high sierra.

in 0.10 you can now check the modifiers in the event as:

void ofApp::keyPressed( ofKeyEventArgs& e) {
    e.hasModifier(OF_KEY_COMMAND)
}

Hmm, still unable to get this to work - I’m in a blank project, OF 0.10.0 with High Sierra;

void ofApp::keyPressed(ofKeyEventArgs& e){

    if (e.key == 's') {
        ofLog() << "Left" << e.hasModifier(OF_KEY_LEFT_COMMAND);
        ofLog() << "Any" << e.hasModifier(OF_KEY_COMMAND);
        ofLog() << "Right" << e.hasModifier(OF_KEY_RIGHT_COMMAND);
    }
}

Event fires if CMD isn’t held down, doesn’t fire if it is held down?

Is this recent commit related?

@autr yes this is a problem with 0.10 in macos. It’s solved already in github and should work with today nightly build and the next official release which should happen soon

I having this problems too. macOS Sierra and OF Github repo.
I tried too to replace ‘eventArgs.key’ to ‘eventArgs.codepoint’ but nothing changes…
(Is not an ofApp, but a class with they own key listeners)

On my if/else tree, only the first two (//action 1 & //action 2) are detected…

Any idea?

void myClass::keyPressed(ofKeyEventArgs &eventArgs)
{
    const int &key = eventArgs.key;
    //uint32_t key_codePoint = eventArgs.codepoint;

    bool mod_ALT = eventArgs.hasModifier(OF_KEY_ALT);
    bool mod_SHIFT = eventArgs.hasModifier(OF_KEY_SHIFT);

    if (mod_SHIFT && key == ' ')
    {
        //action 1
    }
    else if (key == ' ')
    {
        //action 2
    }
    else if (mod_ALT && key == 'p')
    {
        //action 3
    }
    else if (key == 'p')
    {
        //action 4
    }
    else if (mod_ALT && key == 's')
    {
        //action 5
    }
    else if (key == 's')
    {
        //action 6
    }
...
}

void ofxFontAnimator::keyPressed(ofKeyEventArgs &eventArgs)
{
    int key = eventArgs.codepoint;
    //int key = eventArgs.key;

    bool mod_COMMAND = eventArgs.hasModifier(OF_KEY_COMMAND);
    bool mod_CONTROL = eventArgs.hasModifier(OF_KEY_CONTROL);
    bool mod_ALT = eventArgs.hasModifier(OF_KEY_ALT);
    bool mod_SHIFT = eventArgs.hasModifier(OF_KEY_SHIFT);

    ofLogNotice("ofxFontAnimator") << "key: " << key;
    ofLogNotice("ofxFontAnimator") << "COMMAND: " << (mod_COMMAND ? "+" : "");
    ofLogNotice("ofxFontAnimator") << "CONTROL: " << (mod_CONTROL ? "+" : "");
    ofLogNotice("ofxFontAnimator") << "ALT: " << (mod_ALT ? "+" : "");
    ofLogNotice("ofxFontAnimator") << "SHIFT: " << (mod_SHIFT ? "+" : "");
    ofLogNotice();

When pressing ‘p’ key I get:

[notice ] ofxFontAnimator: key: 112
[notice ] ofxFontAnimator: COMMAND: 
[notice ] ofxFontAnimator: CONTROL: 
[notice ] ofxFontAnimator: ALT: 
[notice ] ofxFontAnimator: SHIFT:

But when pressing ALT+‘p’:

[notice ] ofxFontAnimator: key: 960
[notice ] ofxFontAnimator: COMMAND: 
[notice ] ofxFontAnimator: CONTROL: 
[notice ] ofxFontAnimator: ALT: +
[notice ] ofxFontAnimator: SHIFT:

key differs from 112 to 960 so is changing when shouldn’t do.
