    <p>I made a small GUI program with PyGtk for parametrically drawing the frame of a bike (the idea: you move some slider, and the frame gets redrawn with the updated parameter).</p> <p>Somewhere in the code, I must create a slider for each parameter, and I get this very non-pythonic and repetitive code (sorry, I could not get the indentation right while writing this message):</p> <pre><code>def adjustbottomBracketHeight(par): BikeDrawing.p.bottomBracketHeight = par.get_value() painelhoriz.queue_draw() bottomBracketHeightAdjust = gtk.Adjustment(value=BikeDrawing.p.bottomBracketHeight, lower=180., upper=400., step_incr=10.) bbhScale = gtk.HScale(adjustment=bottomBracketHeightAdjust) bbhScale.set_value_pos(gtk.POS_LEFT) bbhScale.connect("value-changed", adjustbottomBracketHeight) bbhLabel = gtk.Label("Bottom bracket height") topcolumn1.pack_start(bbhLabel, False, False) topcolumn1.pack_start(bbhScale, True, True) def adjustseatTubeAngle(par): BikeDrawing.p.seatTubeAngle = par.get_value() painelhoriz.queue_draw() seatTubeAngleAdjust = gtk.Adjustment(value=BikeDrawing.p.seatTubeAngle, lower=60., upper=85., step_incr=0.5) staScale = gtk.HScale(adjustment=seatTubeAngleAdjust) staScale.set_value_pos(gtk.POS_LEFT) staScale.connect("value-changed", adjustseatTubeAngle) staLabel = gtk.Label("Seat tube angle") topcolumn1.pack_start(staLabel, False, False) topcolumn1.pack_start(staScale, True, True) def adjustSeatTubeLength(par): BikeDrawing.p.seatTubeLength = par.get_value() painelhoriz.queue_draw() seatTubeLengthAdjust = gtk.Adjustment(value=BikeDrawing.p.seatTubeLength, lower=300., upper=700., step_incr=10.) stlScale = gtk.HScale(adjustment=seatTubeLengthAdjust) stlScale.set_value_pos(gtk.POS_LEFT) stlScale.connect("value-changed", adjustSeatTubeLength) topcolumn1.pack_start(stlScale, True, True) def adjusttopTubeLength(par): BikeDrawing.p.topTubeLength = par.get_value() painelhoriz.queue_draw() topTubeLengthAdjust = gtk.Adjustment(value=BikeDrawing.p.topTubeLength, lower=400., upper=700., step_incr=10.) ttlScale = gtk.HScale(adjustment=topTubeLengthAdjust) ttlScale.set_value_pos(gtk.POS_LEFT) ttlScale.connect("value-changed", adjusttopTubeLength) topcolumn1.pack_start(ttlScale, True, True) </code></pre> <p>Well with some minor adaptations, I would like (to know how ;o) to "create" this kind of code iterating over a list of the parameter names, something similar to:</p> <pre><code>par_list = ['bottomBracketHeight', 'seatTubeAngle', 'seatTubeHeight'] def widgetize(PARAMETER): """ Create blocks of code where the name PARAMETER would be used to personalize names of handlers, functions, objects, etc. """ for par in par_list: widgetize(par) </code></pre> <p>I read some previous questions/answers and there seems not to be an answer to this specific problem.</p> <p>I appreciate very much your attention</p>

    1. COI had this post edited (thanks, delnan!), but actually only the first two lines after each def belong to the def itself, others are out of the def block. Anyway, it does not change (much) the intent of the task automation, I think.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
