I have them in a frame, and I was wondering if there is a command I could use to remove that frame temporarily. Any suggestions?

BTW, the application is for testing LCD screens. I came up with the following: (in-package :cl-user) (require :ltk) (use-package :ltk) (defun hex-color (r g b) "Return a hexadecimal color string. R G B should be in [0,1]." (flet ((normalize (x) (assert (&lt;= 0 x 1)) (round (* x 255)))) (format nil "#~2,0x~2,0x~2,0x" (normalize r) (normalize g) (normalize b)))) (defun lcd-test () (with-ltk () (let* ((canvas (make-instance 'canvas)) (down nil)) (flet ((set-color (x-rel y-rel) (configure canvas "background" (hex-color x-rel y-rel 0.5)))) (pack canv</pre> Tamas K Papp 2012-04-27T11:53:38 http://comments.gmane.org/gmane.lisp.ltk.user/452 <pre>Hi, is there any way of coloring a create-line, or all lines are black?

I can put events in a queue and use (after ...) to read it periodically in the ltk thread, but it would be easier and more efficient to use the ltk event queue directly. Thank you Syll </pre> Syll 2012-03-12T20:51:02 http://comments.gmane.org/gmane.lisp.ltk.user/450 <pre> Hello I have a few problems/questions with listbox selection (especially multiple selection). * If the listbox does'nt have the focus and I select items with Ctrl+click (including the first one), events from keys are not triggered for this listbox. Is it because the listbox has'nt get the focus at all ? How do i give the focus to the listbox (but not to any item) ? * If I understand this well, there are two special states that can be applied to list items : say "selected" (zero, one or several items) and "focused" (zero or one item). * I can select an item with listbox-select. How can I give the focus to an item ? * I catch selection events with &lt;&lt;ListboxSelect&gt;&gt;. How can I catch "item focus" events ? How can I get the focused item ?

It added tkescaping to tk-princ, where there previously was none. This change broke part of treeview-heading. A patch to make treeview-heading work with the new tk-princ is attached. example: (tk-princ "{stuff}") old result: "{stuff}" new result: "\{stuff\}" new code for old result: (tk-princ '("stuff")) The docstring for tk-princ says "Like princ (format ~a), but convert a lisp list to a Tk list." but the code is now very different. Should the docstring change to match the new code, or should the code be reverted to match the docstring?

I'm having trouble trying to read the properties of widgets. I know for to set them, using configure, but I can't read them back. More specifically, I'm trying to read the width and height of a canvas. Any help would be appreciated.

Could you send me an example script which will (for instance) provide background color and font for a scrollable listbox ? Would much appreciate. Thanks in advance.

Why is that so ? What do size values represent exactly ? I made a grid button rowspan of 2. That button's height isn't exactly 2 times larger than other buttons so it streches the positions of other buttons a bit. Why is that ?
