Greetings all; It appears that there is no longer any support for GTK+2 left in wheezy, at least not that I can find and install, its GTK3 or do without.
I've found this page: <https://developer.gnome.org/gtk3/stable/gtk-migrating-2-to-3.html#id-1.6.3.3.7> But I can't see the connection between what it says, and this xml file used for a camview launcher, and which presumably works ok on a 7 yo *buntu system. But we're stuck on wheezy, which has only glade3, version 3.12.2 TBE. Jessie/Stretch may have a better setup, but I don't know. What I have done for extra display on the pi's jessie install has all been done with the pyvcp stuffs in the user docs, but that is missing so much that doing anything really informative eats up screen real estate like it was a bag of M&M's. Much of the wasted space could go away with two changes, such as the huge white space around the text of a button, and a pin or 2 to set the buttons background color so one could tally the state of that button by the color of the button. But that is not my present problem. I need to convert this bit of xml: <?xml version="1.0" encoding="UTF-8"?> <interface> <requires lib="gtk+" version="2.24"/> <!-- interface-requires gladevcp 0.0 --> <!-- interface-naming-policy project-wide --> <object class="GtkWindow" id="window1"> <property name="can_focus">False</property> <child> <object class="CamView" id="camview1"> <property name="visible">True</property> <property name="camera">0</property> <property name="draw_color">#FFFF00000000</property> <property name="frame_width">640</property> <property name="frame_height">480</property> <property name="circle_size">150</property> <property name="number_of_circles">5</property> <property name="radius_difference">10</property> <property name="autosize">False</property> <property name="cam_settings"></property> </object> </child> </object> </interface> To be executed by glade3. But the reported errors seem to be buried in code well removed from the above xml script. Fed into glade(3) I get errors like missing gladevcp catalog. Draws an orange box with at least 2 showstopper errors. The first is a box advising "Failed to load /home/gene/linuxcnc/configs/GO704fast/camview.glade" Closing that popup, then draws an orange box with 2 buttons, delete and delete-all. In glades upper right corner it shows: Window1 GtkWindow camview1 GladeObjectStub I poked around and set the size of the window, all without affecting the orange box, but without finding a widgit for displaying video in glades many menu's. Since I have a copy of the original, I then saved it, getting this: <?xml version="1.0" encoding="UTF-8"?> <interface> <!-- interface-requires gtk+ 3.10 --> <!-- interface-requires gladevcp 0.0 --> <object class="GtkWindow" id="window1"> <property name="can_focus">False</property> <property name="window_position">center</property> <property name="default_width">640</property> <property name="default_height">480</property> <property name="type_hint">menu</property> <child> <object class="CamView" id="camview1"> <property name="visible">True</property> <property name="camera">0</property> <property name="draw_color">#FFFF00000000</property> <property name="frame_width">640</property> <property name="frame_height">480</property> <property name="circle_size">150</property> <property name="number_of_circles">5</property> <property name="radius_difference">10</property> <property name="autosize">False</property> <property name="cam_settings"/> </object> </child> </object> </interface> Starting linuxcnc then runs, but spits out an error at the maximum screen update rate the machines video can do, showing: VIDIOC_QBUF: Invalid argument VIDIOC_QBUF: Invalid argument So obviously I am in way over my head. And no clue what to do next. Are there more glade widgits I need to install? Or have I once again went down a rabbit hole and found an upset badger? Thanks for any clues on how to proceed.
