tk's Issues

tk decreases load speed of others gems loading after it

If tk is loaded firstly, gems after it would take a long time to load. This becomes extreme with gem rubyXL. Here is the result:

############## first require tk, then rubyXL
t0 = Time.now
require 'tk'
puts Time.now - t0 # 1.35 secs
t0 = Time.now
require 'rubyXL'
puts Time.now - t0 # 58.6 secs

############## first require rubyXL, then tk
t0 = Time.now
require 'rubyXL'
puts Time.now - t0 # 0.28 secs
t0 = Time.now
require 'tk'
puts Time.now - t0 # 2.8 secs

my app use tk as gui. When I use ruby 2.3.1, I do not see this issue. After I upgrade to ruby 2.7.2, the issue shows up. And now I downgrade to ruby 2.6.6, the issue is still there.

Tk::Text listening to a tag covering 1.0 to end stops working after clearing all text (on Mac)

In light of the solution to #36, I wrote code that monitored key presses upon moving around a Tk::Text widget with the arrow keys. It basically registers a listener to <KeyPress> event on a pre-added tag that covers a range of index 1.0 to end.

Here is a code example of this:

require 'tk'

@root = Tk::Root.new

@text = Tk::Text.new(@root).grid
@text.value = "Some giberish repeated many times\n"*20
@text.tag_add('all', '1.0', 'end')
@text.tag_bind('all', 'KeyPress', ->(event) {puts 'key press', event.inspect})

@root.mainloop

You can navigate around the Tk::Text widget using the arrow keys with no problem. It always fires the <KeyPress> listener anywhere in the 1.0 to end range, printing the event information.

Trouble starts once I clear all the text by highlighting with CMD+A and then hitting DELETE. Afterwards, when I type new text and then move the arrow keys around, no firing of the <KeyPress> event happens anymore.

The plot thickens however. If I insert enough new lines, it sometimes starts firing again, albeit temporarily, and then it stops again.

Either way, the functionality seems broken. It is probably broken in ActiveTcl, not in the Ruby code, but I thought I'd report here just in case there is an issue in the Ruby code.

p.s. I am using ActiveTcl-8.6.9.8609.2-macosx10.9-x86_64-93b04018

Can't install tk, something about tcltklib

So my profs doc basically just says "Execute 'gem install tk'", but trying that results in an error that should probably help me install something I'm missing, but I'm not sure if I just lack a certain config option or something?
I basically just installed Ruby via RubyInstaller2, including msys2 with ridk install 1 3 afterwards.
This is the install output:

Two warnings in tk.rb

Warnings:

/root/.gem/gems/tk-0.5.0/lib/tk.rb:1321: warning: method redefined; discarding old to_s
/root/.gem/gems/tk-0.5.0/lib/tk.rb:36: warning: previous definition of to_s was here

Line 36 is:

https://github.com/ruby/tk/blob/master/lib/tk.rb#L36

Line 1321 is:

https://github.com/ruby/tk/blob/master/lib/tk.rb#L1321

Seem to be duplicates indeed, the same line there.

By the way, why is that class TclTkIp extended
twice in the .rb file? Would it not be easier to just use "class TclTkIp"
once, and do all modifications? That code base is a little odd.

extconf.rb ignores config_list.in

Hi, I installed ruby, ruby-dev, tk-dev from the MX Package Installer. If you want the versions I can give them, but as far as I can see it's not important for this issue. gem install tk could not find the libraries, etc. I followed the README.tcltklib and added the build variables to config_list.in, but this made no difference whatsoever, same errors as before.

A closer look at extconf.rb showed that it is not handling the mkmf methods correctly, so I patched extconf.rb, and per the readme I was able to do ruby extconf.rb followed by make and make install. But this did not give me gem. (By the way, even when I gave the correct tclConfig.sh and tkConfig.sh, it still ignored them even though the include and lib paths are in there. But I didn't investigate any further because I could use the include and lib build variables.)

Another gem install tk of course wiped out my ext/tk changes and produced the same errors as before. However, I finally succeeded by appending all my build variables to the command line. Again, I can show the variables, but the point is they are the same as what I put in config_list.in.

My patch to extconf.rb attached. I just started learning Ruby so it's quite possible my patch is not perfect, but I think is a step in the right direction.

How to track text widget insert mark change?

I noticed I could bind to the Tk::Text widget '<Modified>' and '<Selection>' events, but I could not find anything in the tutorial or documentation about how to track text widget insert mark (caret/cursor) changes.

The scenario I need it for is mimicking Word Processor behavior when the user moves the caret (typing cursor) using keyboard arrow or mouse keys and the toolbar formatting options on top (font/size/color/etc...) automatically reflect which style is applied to the current caret position (insert mark) (e.g. 'Bold', 'Helvetica', 'Size 20'). Once I have the insert mark position update event, I know where to get the formatting information from (by querying the tags). I just don't know how to register a listener or callback that would fire whenever the user moves the caret (typing cursor), aka insert mark.

Help would be greatly appreciated.

Help, please?

Binding standard widget events does not work on text widget

Hi,

I tried binding '<KeyPress>', '<KeyRelease>', '<Button-1>' on TkText widget, but they did not result in any firing of changes.

text_test.rb Code example:

require 'tk'
require 'tkextlib/tile'

root = TkRoot.new {title "Text Test"}

text = TkText.new(root) {width 40; height 40}.grid(row: 0, column: 0, sticky: 'nsew')

text.bind('<KeyPress>', -> {puts 'KeyPress'})
text.bind('<KeyRelease>', -> {puts 'KeyRelease'})
text.bind('<Button-1>', -> {puts 'Button-1'})

Tk.mainloop

Help or clarification is appreciated.

bwidget example error

running bwidget example error:

TkPackage can't find package BWidget (RuntimeError)

Ruby crashes during `require 'tk'` on macOS 10.14.6 (Mojave)

When I install the tk gem with gem install tk and then type require 'tk' into irb, the program crashes with the error message below. This appears to be due to a new limitation of the macOS GUI layer.

I am able to work around this by installing ActiveTcl 8.6 and then reinstalling the gem.

I am using Ruby 2.7.0 built from sources using rbenv.

I also attempted to work around this using the tcl-tk package provided by HomeBrew. I was not successful but it is possible I did not correctly specify the version of Tcl/Tk to use.

If you would like, I am willing to submit a pull request that updates the README.md and lists ActiveTcl as a dependency for macOS.

Tk.getMultipleSaveFile does not work on the Mac

The following code snippet works for all dialogs except the last one "Tk.getMultipleSaveFile"

require 'tk'

p Tk.getOpenFile
p Tk.getMultipleOpenFile
p Tk.getSaveFile
p Tk.getMultipleSaveFile

I get this error message:

/Users/andy/.rvm/gems/ruby-3.0.2@glimmer-dsl-tk/gems/tk-0.4.0/lib/tk.rb:2938:in `_invoke': bad option "-multiple": must be -defaultextension, -filetypes, -initialdir, -initialfile, -message, -parent, -title, -typevariable, -command, or -confirmoverwrite (RuntimeError)

	from tmp/test_get_multiple_save_file.rb:6:in `<main>'

It seems like ActiveTcl-8.6.9.8609.2-macosx10.9-x86_64-93b04018.pkg has dropped support for Tk.getMultipleSaveFile

I'll try to confirm this behavior/issue on other platforms once I get a chance.

If it is true, I could perhaps contribute a Pull Request to remove that method (or provide a better error message on the Mac if it is a Mac-only issue)

Tk.mainloop

Environment is cleanly installed Window 7 virtual machine with 2.4.2 rubyinstaller ruby and tk 0.2.0.

Any idea what is going on and how can I work around it?

EDIT: oh, and it happens just sometimes, I would say about 1 in 20 runs.
EDIT2: can reproduce both in 32 and 64 bit version.

Support for Tcl/Tk 8.7

I am a member of the core Tcl/Tk development team and have wanting to test Ruby-Tk against some recent updates to the tip of Tk 8.7 in a Ruby app I maintain. I'm unable to build this gem against Tk 8.7 because it is listed as an unsupported version in extconf.rb. I have tried manually editing the file and also passing 8.7 as a configure flag ("--with-tcltkversion=8.7") but the build system seems to ignore these flags and/or overwrite my locally edited configuration. Can you either add support for Tcl/Tk 8.7 or provide guidance on how to override the restrictions in this gem? I understand that Tk 8.7 is not yet released, but it is maturing rapidly and it would be helpful to be able to build this gem against that version. Thank you.

tk on windows with ActiveTcl and ruby 3.2 crashing

Hi, I've followed the guide at https://tkdocs.com/tutorial/install.html#install-win-ruby.

I've installed the latest ruby at [Ruby+Devkit 3.2.3-1 (x64)] https://github.com/oneclick/rubyinstaller2/releases/download/RubyInstaller-3.2.3-1/rubyinstaller-devkit-3.2.3-1-x64.exe) and the latest ActiveTcl install ActiveTcl-8.6.13.0000-MSWin32-x64-559160e0.msii.

I've set the env vars, copied the dll's to ruby's bin as said in the guide.

The crash seems to have no further information other than it's just failed. Any ideas? Thanks.

How i can install Tk !?

how i can install tk on ubuntu
i execute this command "gem install tk" but it failed

Small warnings issued by the tk gem - could these be removed by someone with commit access?

Hello there.

Requiring the tk-gem leads to lots of warning messages.

I'll go through them:

https://github.com/ruby/tk/blob/master/lib/tk.rb#L821

/root/.gem/gems/tk-0.3.0/lib/tk.rb:821: warning: assigned but unused variable - id

The line:

id = "c" + TkCore::INTERP._ip_id_ + TkComm::Tk_IDs[0]

I would probably simply add an explicit return, or just "id" as the last value there:

return id

https://github.com/ruby/tk/blob/master/lib/tk.rb#L3490

/root/.gem/gems/tk-0.3.0/lib/tk.rb:3491: warning: assigned but unused variable - e

The line:

rescue => e

I would either remove the "=> e" part, or if you want to keep it:

rescue => _e
rescue => _error
rescue => _exception

Something like that.

Hmm many more such small warnings, at lines
3551, 3807, 3951, 4054.

Also a method is redefined here:

/root/.gem/gems/tk-0.3.0/lib/tk.rb:1369: warning: method redefined; discarding old to_s

Not sure why.

At line 887:

/root/.gem/gems/tk-0.3.0/lib/tk.rb:887: warning: instance variable @cmdtbl not initialized

This one is not initialized. Perhaps a reset() method or something like this
could be used to initialite all these variables.

/root/.gem/gems/tk-0.3.0/lib/tk.rb:2533: warning: instance variable encoding_table not initialized

Then another small warning in winfo.rb:

/root/.gem/gems/tk-0.3.0/lib/tk/winfo.rb:242: warning: parentheses after method name is interpreted as an argument list, not a decomposed argument

And some warnings like:

/root/.gem/gems/tk-0.3.0/lib/tk.rb:2855: warning: instance variable @encoding not initialized

Perhaps if someone with commit rights could go through these? These are mostly trivial
to fix; not sure if it is possible to do so via the web-interface.
