Re: FFT MARKER

[Derek Kozel]

    Hello Alberto,
    
    No, no one has implemented markers for the QT GUIs. We have mentors
    willing to help anyone interested in improving the GUIs, but no one
    has started coding. We also have a Google Summer of Code project
    idea listed for this, but no students have applied for it.
    
    Here's the summary of that project proposal, in case anyone is
    interested.
    
    QT Widgets Improvements:

The gr-qtgui in-tree component provides some QT widgets for signal visualization. This component needs some improvement to become more useful.
This project is cleanly divided into several sub-projects:

• Add new widgets
  • Compass display (e.g. for direction-finding applications)
  • MPEG display (e.g. for video demod output)
  • Matrix sink (e.g. for radar Doppler/range plane visualization, or 2D-equalizer taps visualization)

• Improve current widgets
  • Better code structure to make the current widgets more manageable, extensible and remove code duplication between widgets
  • More Control Panels on other widgets (follow lead on the frequency sink)
  • Improve UI, make more intuitive, more power to mouse users
  • Set trigger point with mouse

• Integration / Support for QT Creator
  • QML design
  • Allow to build full GUI applications from, say, GRC

Prerequisites

• Familiarity with QT is essential.
• Widgets are written in C+, so some C+ knowledge is also required.
• Python skills are highly useful.
