Panel Control to Draw or Edit Marker Waves

Thu, 04/23/2020 - 09:24 am

This uses a panel to create, edit, and clear a drawing wave. The waves are created in the current data folder and have the names drawwaveY and drawwaveX.

// a static constant to set the panel name
StrConstant k_panelname = "WaveDrawEdit"

// change this to set your desired marker style to create and edit the marker wave
Function set_DrawMarkerStyle(frontimgwin)
    string frontimgwin

    // set your desired marker style here
    ModifyGraph/W=$frontimgwin mode=3,marker=8,msize=5,mrkThick=2

    return 0
end

// call this to create the panel
Function show_DrawControlPanel() : Panel

    NewPanel/W=(50,50,250,100)/N=$k_panelname as "Wave Draw/Edit"
    ModifyPanel/W=$k_panelname fixedSize=1,noEdit=1
    Button bDrawControl,pos={15,10},size={50,20}, fSize=14, userdata(draw)="start",proc=ButtonProc,title="Start"
    Button bEdit,pos={70,10},size={50,20},fSize=14,proc=ButtonProc,title="Edit",disable=2
    Button bClear,pos={130,10},size={50,20},fSize=14,proc=ButtonProc,title="Clear",disable=2
   
    return 0
end

// do or end the drawing or editing
Function do_Draw()

    string udata, frontimgwin
   
    udata = GetUserData(k_panelname,"bDrawControl","draw")
    frontimgwin = WinName(0,1,1)

    SetDrawLayer/W=$frontimgwin ProgFront
    GraphWaveEdit/T=1/W=$frontimgwin drawwaveY

    return 0
end

                    do_draw()
                    break

            endswitch
            break
        case -1: // control being killed
            break
    endswitch

 draw wave edit panel

With one clever change, the system now keeps the markers for the drawing also when clicking the End... button. It first toggles to GraphWaveEdit/T=1, then toggles to GraphNormal.
