Hi,
After appending a row in an FXTable, I’d like to scroll the FXTable to
the last line of the FXTable, to make sure the new row is visible.
I’m using this kind of code:
def onInsertRow(sender, sel, ptr)
@table.appendRows(1, true)
@table.setPosition(0, -1000) # I never have more that 1000 lines
in the table!
end
The problem is that I’m unable to scroll until the last line, only the
line *** before the last line ***. Apparently, it’s a “timing” problem:
when position is set, the line append is not completely “committed” to
the GUI.
Called separately, @table.setPosition(0, -1000) works just fine, as you
can see in this test:
#!/usr/bin/env ruby
require ‘fox16’
require ‘date’
include Fox
class TableWindow < FXMainWindow
def initialize(app)
# Call the base class initializer first
super(app, “Table Widget Test”, :opts => DECOR_ALL)
# Tooltip
tooltip = FXToolTip.new(getApp())
# Menubar
menubar = FXMenuBar.new(self, LAYOUT_SIDE_TOP|LAYOUT_FILL_X)
# Separator
FXHorizontalSeparator.new(self,
LAYOUT_SIDE_TOP|LAYOUT_FILL_X|SEPARATOR_GROOVE)
# Contents
contents = FXVerticalFrame.new(self,
LAYOUT_SIDE_TOP|FRAME_NONE|LAYOUT_FILL_X|LAYOUT_FILL_Y)
frame = FXVerticalFrame.new(contents,
FRAME_SUNKEN|FRAME_THICK|LAYOUT_FILL_X|LAYOUT_FILL_Y, :padding =>
# Table
@table = FXTable.new(frame,
:opts =>
TABLE_COL_SIZABLE|TABLE_ROW_SIZABLE|LAYOUT_FILL_X|LAYOUT_FILL_Y,
:padding => 2)
@table.visibleRows = 10
@table.visibleColumns = 4
@table.setTableSize(20, 14)
# Initialize column headers
(0...12).each { |c| @table.setColumnText(c, Date::MONTHNAMES[c+1])
}
# Initialize row headers
(0...20).each { |r| @table.setRowText(r, "Row#{r}") }
# File Menu
filemenu = FXMenuPane.new(self)
FXMenuCommand.new(filemenu, "&Quit\tCtl-Q", nil, getApp(),
FXApp::ID_QUIT)
FXMenuTitle.new(menubar, “&File”, nil, filemenu)
# Manipulations Menu
manipmenu = FXMenuPane.new(self)
FXMenuCommand.new(manipmenu, "Insert Row").connect(SEL_COMMAND,
method(:onInsertRow))
FXMenuCommand.new(manipmenu, “Go to last row”).connect(SEL_COMMAND,
method(:onCmdGoToLastRow))
FXMenuTitle.new(menubar, "&Manipulations", nil, manipmenu)
end
def onCmdGoToLastRow(sender, sel, ptr)
@table.setPosition(0, -1000)
end
def onInsertRow(sender, sel, ptr)
@table.appendRows(1, true)
@table.setPosition(0, -1000)
end
Create and show this window
def create
super
show(PLACEMENT_SCREEN)
end
end
Start the whole thing
if FILE == $0
Make application
application = FXApp.new(“TableApp”, “FoxTest”)
Make window
TableWindow.new(application)
Create app
application.create
Run
application.run
end
Any idea how I can do that?
Thanks!
