Hi guys, I'm quite new with Inkscape so forgive me if the question is trivial.I'm developing an extension using Tkinter,it works well but the dialog is modal and I cannot do anything else with Inkscape while the extension is open. Is there a way to avoid this problem?Thanks a lot.

Rendering regressions in 0.92
by Bryce Harrington 24 Aug '16

24 Aug '16

Following up on the revert of the Gtk3 canvas refactoring to resolve the performance regression, it looks like this may have caused a few side effects: Canvas drawing errors: https://bugs.launchpad.net/inkscape/+bug/1608152 Crash on file open: https://bugs.launchpad.net/inkscape/+bug/1607698 Crash resizing application windows: https://bugs.launchpad.net/inkscape/+bug/1608216 Unfortunately these are all deemed blockers. :-/ Anyone have ideas on what might be the problem on these? Any chance there are fixes in trunk which need ported? Bryce

--query-all command line option
by Jordan Henderson 23 Aug '16

23 Aug '16

Hello, i am new to the source code, although I have worked with C++ before. I am trying to understand why --query-all does not return all objects that show a visible box when the SVG document is viewed using Inkscape. Specifically, a flowRoot will have a box for it when that element is clicked on in the XML editor, showing an x,y,w,h but it does not appear in the output from a --query-all. thank you for your time and patience, Jordan -- Jordan Henderson

C++11 Best Practices
by Tavmjong Bah 18 Aug '16

18 Aug '16

Hi all, Now that we can use C++11 in trunk (yeah!), what are the best practices? Are there parts of C++11 we still want to avoid? I started to think about this as I noticed in the code some places with perhaps over aggressive use of 'auto'. It seems to me that 'auto' should be reserved to places where it replaces a long, already unreadable iterator type. But it should not be used to replace simple types as this reduces the readability of the code, especially to someone not familiar with the code. For example, I don't see any benefit of replacing: GtkWidget* mywidget = someFunction(); by auto* mywidget = someFunction() Tav

Bugs, ,bugs, and more bugs: PVS Studio
by Michael Soegtrop 16 Aug '16

Dear Inkscape Developers, I would be careful with the this!=NULL statement for bool SPLPEItem::performPathEffect as far as I can tell, this is not a virtual function, and there is no reason why the this pointer of a non virtual function should not be NULL. One can call a non virtual member function on a NULL pointer. Not very nice, but some people put such checks into the code as extra safety check on purpose and some even use tricks like calling a function on NULL pointers on purpose, e.g. for saving a lot of checks when the function is called. Best regards, Michael

Text and Font Panel
by Thangalin 13 Aug '16

13 Aug '16

Hi, There are a number of issues with the Text and Font (Ctrl+Shift+T) panel, including: * Loading. Loading all system fonts can, in some cases, significantly reduce application launch time. * Memory. Loading fonts eats through memory. * Performance. It can be sluggish to scroll through hundreds of fonts. * Panel width. Long font names can cause the Text and Font panel (when docked) to take up half of the drawing area. The issues include: * https://bugs.launchpad.net/inkscape/+bug/1400273 * https://bugs.launchpad.net/inkscape/+bug/1612985 (https://launchpadlibrarian.net/278803244/wide-font-panel.png) * https://bugs.launchpad.net/inkscape/+bug/488247 * https://bugs.launchpad.net/inkscape/+bug/418726 * https://bugs.launchpad.net/inkscape/+bug/430328 * https://bugs.launchpad.net/inkscape/+bug/322113 I'd like to propose some cosmetic changes to the Text and Font pane that could, perhaps, resolve all of these issues. See attached (http://i.imgur.com/Jx9Suy2.png). 1. Remove the word "font" (the tab menu gives context). 2. Add horizontal scrollbars to account for long names. 3. Add a Preview list box that shows the fonts in the view port for the Family list box. This means that fonts don't have to be loaded until the Family list box view port displays them. Rather than load the fonts at startup, load them at runtime as needed. It's probably reasonable to apply a micro delay (say 50ms) so that scrolling through the Family list box is smooth and fonts are only loaded/rendered when the user stops scrolling for 50ms. Remove the preview from the Family list box. 4. Allow the user to provide custom preview text. Preview list box should present this text. Put a reasonable limit (e.g., 30 characters) on this. Perhaps this could be a select drop-down with various phrases that show all the letters (e.g., "Grumpy wizards...", "...lazy dog", "Cwm fjord...", "0123456789", plus a short history past user-defined phrases). 5. Allow the user to toggle the Preview list box. This could have a significant performance increase for people who don't need to preview all the fonts all the time. It could also save lots of memory. Additionally, it would free up screen real estate as the panel width would decrease by the Preview list box width. 6. Allow user to change font size and units. The size is shown as a drop-down in the mock-up, but the user should also be able to type in a specific size (e.g., 9.5) as per existing functionality. 7. Maybe allow the user to disable the scroll lock between the Family and Preview list box areas so that they can vary independently. Activating the lock automatically updates the Preview list box to reflect the Family list box view port. 8. Provide beefier handles to resize the pane. Resizing it should increase the height of the Family/Style/Preview list boxes, pushing the options (justification, size, space, etc.) down. Clicking on three tiny dots can be a daunting task for people with shaky hands... 9. Never disable the Set as Default / Apply buttons. If pressing the buttons won't do anything, then fail silently. Otherwise, always let the user click them and try to perform the appropriate action. Currently there's a bug where, in some cases, if the user changes the font size (but not the font), the Apply button remains disabled. Removing the code for disabling these buttons should simplify the source code and possibly force the developer to address the font size changing bug. Thoughts?

Hi Devlin, Please file a bug report for this problem, and include an example .svg file demonstrating the issue. The reason the post was rejected is because we only allow list members to post.

Snap for Inkscape
by Ted Gould 12 Aug '16

12 Aug '16

Howdy, So I (with some help from others) was trying to make a Snap for Inkscape. My goal was to make it so that, when we have it, we can get the 0.92 release to Ubuntu users on 16.04 LTS. Snaps do work for other Linux distros, but it is preinstalled on Ubuntu. The snap that I built is available here: https://code.launchpad.net/~ted/+snap/inkscape I have it built for i386 and amd64 right now for testing, but we can enable other architectures (armhf? arm64?) when we start getting to a real build. The snap is unoptimized and needs further testing, but I'd love it if other people could install it and send me their results. One major thing missing is the Python libs for the extensions. That's next on my TODO. For information on installing snapd on a variety of Linux distros you can get info here: http://snapcraft.io/docs/core/install Eventually I'd like to get a per-commit build going for the GTK3 release on the edge channel, but trying to get the stable release version working first. Thanks for feedback, Ted ##SELECTION_END##
