[fxruby-users] Text color for individual items in FXTable

Hello,

 

I would like to set text colors for individual items in an FXTable.
FXTable has a textColor accessor, but it applies to every item, not to
individual items.  So I subclassed FXTable and overrode createItem to
return a subclass of FXTableItem in which I override drawContent.  One
of drawContent''s parameters is the device context dc, but when I call
dc.drawText in my customized drawContent, nothing is drawn on the
screen.  I know the method is being called.  What might be wrong?  Has
anyone else managed to set text colors for individual table items?

 

Thanks for any help,

 

Tim

[fxruby-users] Text color for individual items in FXTable

You can use the FXTable''s setCellColor to acheive a nice alternating
look as shown in the screenshot on the FXRuby website. However, it
sounds like you''re trying to set individual cells which I
haven''t tried.

    # Table
    @table = FXTable.new(frame,
      :opts =>
TABLE_COL_SIZABLE|TABLE_ROW_SIZABLE|LAYOUT_FILL_X|LAYOUT_FILL_Y,
      :padding => 2)
      
    @table.visibleRows = 20
    @table.visibleColumns = 8

    @table.setTableSize(50, 14)

    @table.setBackColor(FXRGB(255, 255, 255))
    @table.setCellColor(0, 0, FXRGB(255, 255, 255))
    @table.setCellColor(0, 1, FXRGB(255, 240, 240))
    @table.setCellColor(1, 0, FXRGB(240, 255, 240))
    @table.setCellColor(1, 1, FXRGB(240, 240, 255))

[fxruby-users] Text color for individual items in FXTable

Right - I''m trying to set text colors for individual cells, not
background colors for alternating rows and columns.  In the code below,
I don''t even try to set colors, but just override drawContent with a
Ruby translation of FXTableItem::drawContent from FXTable.cpp in the FOX
distribution.  But no text appears in the cells.  Am I missing
something?

Thanks, Tim

[fxruby-users] Text color for individual items in FXTable

Good news, everybody!  I found a thread on comp.lang.ruby about a
similar problem setting fonts for individual table items:

http://groups.google.com/group/comp.lang.ruby/browse_thread/thread/b568f
66fe08a69a5/625209163eb11dd8?#625209163eb11dd8

Like me, he found drawContent''s dc parameter unusable.  His solution
was
to create a new one with FXDCWindow.new.  That worked for me and I can
now set individual text colors; code below.  If no one objects, I''ll
file a bug report about the unusable dc parameter.

Regards, Tim

require ''fox16''; include Fox

class CustomTableItem < FXTableItem
  attr_accessor :color

  def drawContent table, unusable_dc, x, y, w, h
    FXDCWindow.new(table) {|dc| 
      if @color and not selected?
        dc.setForeground @color
        def dc.setForeground color
          # stop super from setting color back
        end
      end
      dc.setFont unusable_dc.getFont
      super table, dc, x, y, w, h
    }
  end
end

class CustomTable < FXTable
  def createItem *parameters
    CustomTableItem.new *parameters
  end

  def setItemTextColor row, column, color
    getItem(row, column).color = color
    updateItem row, column
  end
end

app = FXApp.new
main = FXMainWindow.new app, ''Test''

table = CustomTable.new main
table.setTableSize 2, 2
table.visibleRows = 2
table.visibleColumns = 2

table.setItemText 0, 0, ''one''
table.setItemTextColor 0, 0, FXRGB(255, 0, 0) # red
table.setItemText 0, 1, ''two''
table.setItemTextColor 0, 1, FXRGB(0, 255, 0) # green
table.setItemText 1, 0, ''three''
table.setItemTextColor 1, 0, FXRGB(0, 0, 255) # blue
