[Pythoncard-users] Color in Lists

[Daryl F. <fly...@sb...>]

I've been playing with PythonCard for about a week now and I have to say I'm
impressed.  It seems very well thought out.

I do, however, have one issue.  I would like to set the text colour of
individual items in a list.  Right now I'm doing a whole lot of rework just
to get around having to do this, but it is becoming fairly difficult at this
point.  Is this even possible (without doing too much damage)?

IIRC, I don't think it is supported in the underlying wx.ListBox 
control used by the List component, but is supported by the wx.ListCtrl 
which is underneath the MultiColumnList. You can check what the 
wxWidgets docs say or find what you want to do in the wxPython demo and 
then you'll have to call the appropriate wxPython methods to set the 
colors.

[Pythoncard-users] TextArea - word wrap- how to?

[<gre...@co...>]

Hi,

I can't seem to get the word wrap to happen in a textarea.  It shows the 
portion of text that fits in the first row of the textarea but cuts off 
everything after that.  I've included the code I'm using at the end of 
this email (ignore my email's word-wrapping if possible)

Should I remove the existing '\r' s and '\n's from my text, could that 
be confusing the textarea?

Thanks,

Greg


This is the definition:
		widgetDefn={'type':'TextArea',
                                 'name':'txt'+ column[0],
                                 'position':(xPosWidget, yPos),
                                 'size':(255*9, NumRows*rowHeight),
                                 'alignment':'left',
                                 'border':'3d',
                                 'editable':False,
                                 'enabled':True,
                                 'text':'',
                                 'toolTip':'Values in this record field',
                                 'visible':True}
Here is where it is filled:
	 self.components[item].text=str(row[widgetCount])

And row[widgetCount] text is below:
'I saw a truck today.  There  was a man with a beard driving it.
   It had a license plate that said "god".  I found myself wondering if 
god was a
ctually in that truck.  The man looked kind of non-real.  I drove up 
next to him
  but he didn\'t see me.  Then he turned off onto 95.  I really wanted 
to follow
him but he was going south and I have to go north.  And besides, we 
wouldn\'t ha
ve a road for him to drive on if everyone spent all their time following 
him. \r

That's  2295 pixels wide, so the text below wouldn't need to wrap to fit=20
inside it.

note - the text area will NOT be confined to the screen size, or the window=
=20
size, or ..... it will be 2295 pixels wide.

Okay, here's my solution to this.  Please note, I'm sure that many other
people have better ways, but this works for me.

First, the List must become a MultiColumnList.  As a bonus, I was able to
remove my static text label and use the column label instead.  Then each
item is applied a wxCOLOR.  Below is a simple example.

Start up the resourceEditor.  For this example, build a new 'Standard
Template with File->Exit menu'.  Plop down a MultiColumnList and give it the
name 'MultiColumnList'.  Set it's size to be about 180 x 175.  Save the
file.  The .rsrc.py file should contain the following down near the bottom:
{'type':'MultiColumnList',
    'name':'MultiColumnList',
    'position':(15, 10),
    'size':(182, 169),
    'backgroundColor':(255, 255, 255),
    'columnHeadings':[],
    'font':{'faceName': 'Tahoma', 'family': 'sansSerif', 'size': 8},
    'items':[],
    'maxColumns':20,
    'rules':1,
    },

Now open up the .py file. and change it to:

from PythonCard import model
from wx import Colour

COLOURS = [Colour(0, 0, 0),       Colour(0x66, 0, 0),    Colour(0xff, 0, 0),
           Colour(0xff, 0x99, 0), Colour(0xff, 0xff, 0), Colour(0, 0xff, 0),
           Colour(0, 0, 0xff),    Colour(0x99, 0xff, 0), Colour(0xcc, 0xcc,
0xcc),
           Colour(0xff, 0xff, 0xff)]

class MyBackground(model.Background):
   def on_initialize(self, event):
      Items = "Bad Beer Rots Our Young Guts But Vodka Goes Well".split(" ")
      self.components.MultiColumnList.columnHeadings = "Color Code"
      self.components.MultiColumnList.items = Items

      for Item in range(len(self.components.MultiColumnList.items)):
         self.components.MultiColumnList.SetItemTextColour(Item,
COLOURS[Item])

if __name__ == '__main__':
   app = model.Application(MyBackground)
   app.MainLoop()

Here we build a list of colours called COLOURS.  Inside the on_initialize
method, the column is given a label and then populated with items.  Finally,
the for loop goes over each item and sets it's color.  Please note, this is
just a funny little example.  If you populate the list with more items than
we have colors Bad Things will happen.  I suppose you could do a max of
len(Items) and len(COLOURS) if you were worried about that...

Hope this helps,
-Daryl

IIRC, I don't think it is supported in the underlying wx.ListBox
control used by the List component, but is supported by the wx.ListCtrl
which is underneath the MultiColumnList. You can check what the
wxWidgets docs say or find what you want to do in the wxPython demo and
then you'll have to call the appropriate wxPython methods to set the
colors.

Thanks Daryl,
just as an FYI you don't have to use the Colour class, wxPython will 
accept a variety of formats and convert appropriately. You can use the 
same kind of representations you would in PythonCard.

COLOURS = ['black', '#660000', 'red',
            (255, 0x99, 0), (255, 255, 0), 'green',
            'blue', (0x99, 0xff, 0), '#cccccc', 'white']

is equivelant to

COLOURS = [Colour(0, 0, 0),       Colour(0x66, 0, 0),    Colour(0xff, 
0, 0),
            Colour(0xff, 0x99, 0), Colour(0xff, 0xff, 0), Colour(0, 
0xff, 0),
            Colour(0, 0, 0xff),    Colour(0x99, 0xff, 0), Colour(0xcc, 
0xcc,0xcc),
            Colour(0xff, 0xff, 0xff)]

All of the named colors that wxPython supports as well as their RGB 
values are defined in wx/lib/colourdb.py. The names are not 
case-sensitive.
