I am seeking help with an Iwidgets problem
in [TCL]
|
From: Larry W. Virden on 26 May 2010 11:16 I've seen this problem in both Tcl 8.4 and 8.5. The following code is an attempt to distill the problem into a small coherent example. The environment is this: Users have Cygwin on their Windows desktop, ssh into a SPARC Solaris machine, and run the real application on the SPARC, displaying back through Cygwin's X server. (Right now, there is also some verification going on using Exceed on the Windows desktop instead.) The simplified example displays a large window with a single tab at the bottom. When the user clicks the tab, a "File" widget appears at the top of the box. Clicking on the entry's down arrow on the right _should_ display a drop down menu of a series of file names (thisIsFile1 this IsFile2 etc.). Instead, what we see is a single column - not even wide enough for 1 character. displaying the first part of the t in the file name. I would like to ask: 1. Does anyone on some platform other than Windows see the same thing 2. Does anyone have an idea what needs to be done so that the entire file name is displayed? Is this a problem in Tk, Itk, Iwidgets, or the application? Thank you for your help. package require Tk package require Itcl package require Itk package require Iwidgets wm title .

I too am using -multiwindow, so that matches. I am uncertain whether the Exceed users are going to be seeing the same behavior or not. What version of the Cygwin server are you using? I have 1.6.5 and I discovered today that is pretty old. If you have a newer version, then I will know that upgrading at least through that level won't help the situation.

So, does anyone have any ideas on what might be causing cygwin's x server, in multiwindow mode, to display comboboxes in this way? It seems like there must be some sort of sizing information that is not being supplied by the iwidgets combobox/tk underlying widgets but that the server is using. |
