Experimenting with setMask and widgets

[Vittorio]

Hi there,
I must admit it. I was so bored today that I started playing with Mixxx code.
One of the things I did was to play with setMask.
This last allows to draw a custom shape for a widget, so that I could drop that ugly vertical line which is used to display current position on the waveform.
What happens is that skin seems to be overlapped with waveform view.
Although I am not so good in designing, I think that the result is quite eyecandy:

Mixxx with setMask on waveform widget

MixxxSetMask.png (168.79 KiB) Viewed 869 times

Visual Waveform detail

MixxxSetMaskZoom.png (30.29 KiB) Viewed 869 times

Of course, such feature does allow every kind of shapes.
It is so ugly just because I am not so good in using gimp
What do you think about?

Hey, it looks great and innovative. It is better instead of using a simple line between the waveform. How did you do it?

Hey Irwin,
Thanks!
Well, to obtain this result I had to edit few lines of code.
The trick is to edit Deere skin background to have a custom shape for visual waveform.
Select all the interior of such shape and save it to a custom png.
Open Mixxx source code with an editor and add a WGLWaveformViewer::resizeEvent to wglwaveformviewer where such custom png is used to set a custom shape for the widget. Say:

Code: Select all

void WGLWaveformViewer::resizeEvent(QResizeEvent *event){
    QPixmap pixmap("CustomPng.png");
    if(pixmap.isNull())qDebug()<<"Pixmap not loaded";
    setMask(pixmap.mask());
}


Compile it and tweak a bit skin.xml to fit visual in such a way that "spikes" do correspond to vertical position line.
When done, one can delete position line by editing again Mixxx code.
Of course, mask file is hardcoded, since it just experimenting.
But I may write a patch if it results interesting.

You should become a dev for this software, they can always use the help.
