Re: Wx:Grid Setting Cursor Position

Norbert Lange — 2012-05-24T15:27:47

It took a bit of time and experimenting, but this seems to work, for 
anyone
else who's maybe run into the same issues.  Here's the code I came up
with for scrolling to a grid position given a cell row and column.  I
hope someone finds it useful.

Wx:Grid Setting Cursor Position

Norbert Lange — 2012-05-22T21:29:03

I'm using the grid widget with an underlying GridTableBase and trying to
implement a "Find" button which would cause the current cursor position
to go to the next matching cell.  I'm wondering if there's an easy way
to do it?  I'm playing with the Grid.select_block_row(),
Grid.set_grid_cursor() and Grid.scroll() methods, but the results are a
bit erratic.

Is there a better way to do this than using Grid.move_cursor_down/right?

Thanks,
Norbert

Re: Grid Cell Background Colour

Norbert Lange — 2012-05-18T17:15:49

Update:  I finally got this working.  In case anyone else runs into the 
same thing, I finally realized I needed to override the set_attr and 
get_attr methods in my Table subclass.

I should probably also have mentioned, the Table object is derived from 
Wx::GridTableBase.

Grid Cell Background Colour

Norbert Lange — 2012-05-17T22:02:10

On to my next question.  :-)

I've been trying to get the cell background colour to work for a
Wx::Grid
control.  Setting a default background colour works, but using the
set_cell_background_colour method for an individual cell doesn't.
Following is a short snippet of what I'm trying to do (essentially
highlight cells that don't match):

  columnNames = Array.[]("Col1", "Col2", "Col3")
  row1 = Array.[]("A", "B", "C")
  row2 = Array.[]("X", "Y", "Z")
  resultSet = Array.[](row1, row2)

  table = Table.new(columnNames, resultSet)
  grid = Wx::Grid.new(panel, -1)
  grid.set_table(table)
  < at >grid.set_cell_background_colour(1, 1, Wx::RED)

Any help is greatly appreciated.

Notebook Change Page Event Handling

Norbert Lange — 2012-05-16T20:18:23

I'm still a bit new to Ruby, but have been using WxRuby for a couple of
months now.  I've created a notebook with a few pages, and am having a
tough time understanding how to implement an event handler that would
get called whenever the page gets changed.

Would someone be kind enough to post a simple example?

Although not directly helpful, I just thought I would post that I got

It's not something that can be worked round directly in Ruby, I think. 
The best thing to do would be to post a bug - it isn't a difficult fix

Printing (on Windows) without using any print dialogs

Carsten Gehling — 2012-04-17T11:33:03

I am developing a Windows application that is going to print on
envelopes (C5 and C6 envelopes) based on data, that is retrieved from an
external order system.

The application is going to be running mostly automatic. So I need to
bypass the print setup dialog, that is normally used when printing with
wxRuby.

This presents me with some problems. I create a Wx::PrintData object to
control the printer, paper size, orientation, etc. like this (the
printer name is just an example, I hold it in a config file):


pd = Wx::PrintData.new
pd.set_printer_name("Dell 3110cn")
pd.set_paper_id(Wx::PAPER_ENV_C6)

The last line gives me this error:

`set_paper_id': Expected argument 1 of type wxPaperSize, but got Fixnum
31 (TypeError)

The type wxPaperSize is not defined (as far as I can see), but it iś
something coming from the SWIG interface. I don't really know how to
solve this.

If outputting the existing paper_id I get:


#<SWIG::TYPE_p_wxPaperSize:0x2173c40>

Which doesn't really make it any clearer for me. So how should I do
this?

Re: getting wxRuby to work on Ubuntu 11.10

Alex Fenton — 2012-04-13T08:53:17

Thanks - I totally agree. Chauk-mean has done great work to get things 
working with SWIG 2.x, and that should be maintainable now. There is a 
bigger job up ahead of porting to wxWidgets 3.0, which will get the 
library working again properly on OS X.


What problem did you run into with the event binding?

Our Ohloh page has a list of SVN commits: 
https://www.ohloh.net/p/wxruby/commits

You could have a browse through that - some of the older ones will 
involve adding classes.


There's some stuff on the wiki already on adding a class - is that what 
you meant by a 'lib'? Anyway, just posting to say that I'm around, even 
if I might be a bit slow to reply...

Sorry missed this as Spam Assassin snatched it due to the relay and  
lack of rDNS.


I've been absent as I've been hoping job sites so haven't made much  
progress in getting the wx 2.8.11 contrib lib for property grid added  
in my local dev files. My test case is from a working wx C++ project.  
I have the entire interface sans that plus a custom control working in  
wxRuby.

I hit a wall in my lack of experience with SWIG and getting the events  
correct. I am very intrigued by the post of someone committing a patch  
getting SWIG 2.x working. I really want to try and find a commit or  
*something* I can read a diff where a dev added a control so I can see  
the process.

As an aside, implementing a custom wxRuby class to "roll my own"  
property grid was easy with the current control support, however that  
defeated the purpose of learning. Maybe we can sweet talk a dev into  
posting a diff or short tutorial on adding a lib. Seeing the walk  
through of adding a small lib (maybe making a custom control with a  
couple I/O and event functions) will be tremendously helpful.

If I can get through the wall, I'll be happy to post the entire app as  
a tutorial.

Hi,



SWIG-2.0.x support has been added in SVN (in the
branches/wxruby_2_0_stable).
It's not yet delivered as a release but you can get the sources from SVN.
Like me, Alex, the lead developer, has been away from the project for a
long while.

Cheers,

the current SVN trunk, but at least for the latest stable release
2.0.1 you’re limited to SWIG version 1.3.38 and there’s no support for
wxWidgets 2.9.

Kevin McCaughey — 2012-04-07T23:11:58

I am coming at this from C/C++ and have fallen in love with Ruby. After 
much reading of this forum and asking on IRC, I think it would be a real 
shame to have wxRuby slide into oblivion.

I have a lot of time on my hands at the moment (unless my current 
project takes off quicker than expected). I have never committed 
anything to Open Source, but I am going to start here if I can.

To the guy posting above as guest - if you access this via 
ruby-forum.com you can set up a username easily and it means we know who 
the knew committer is! (By persona at any rate - which is helpful)

Just how much of this is a SWIG problem and how much is down to wxRuby 
just not being worked on? Even a ballpark percentage split would be 
helpful to know from one of the previous developers. If it's really just 
a SWIG problem then maybe our time is indeed better spent there for the 
moment?

wxAuiFloatingFrame get_parent not supported

2012-03-01T21:27:46

ruby 1.9.3, wxWidgets 2.8.11, wxruby 2.0.1, ubuntu 11.10 x86_64

To get my sizers to update everything in some cases I need to:

self.parent.send_size_event

Self is a derived class of Wx::ScrolledWindow

The scrolledWindow is embedded in an AUI managed pane. While the pane  
is attached, the parent class is Wx::AuiFrame. At this point I can  
trigger an event that in turn calls the send_size_event and things are  
good.

If I detach the pane and fire the event that calls the  
self.parent.send_size_event I get the below error:

/wx/accessors.rb:48:in `get_parent': Error wrapping object; class  
`wxAuiFloatingFrame' is not supported in wxRuby (NotImplementedError)

I am thinking that the floating frame is a top frame and there isn't  
an application parent or I simply (hah) need to implement get_parent  
in some manner to deal with the size event feedback I want.

My current theory is I need to find a proper hook at some level above  
my embedded window. I am having trouble finding a hook or other method  
to get around the above fault. I will continue to try and find a wedge  
into the AuiFloatingFrame but think that route may be beyond my  
understanding at this time to do some surgery on the SWIG stuff  
(working on that).

Any assistance is very much appreciated. In the meantime I will  
continue pluggin away at it. If needed, I can whittle down my app to  
showcase the problem.

Have a good one!
