how to build?
by Martin Vidner 18 Oct '13

18 Oct '13

Hi, I plan to look more into libyui and I am starting by porting libyui-qt to Qt5. (So far I have been more or less fighting with CMake) What is the status of https://github.com/libyui/libyui-buildtools , compared to https://github.com/libyui/libyui/tree/master/buildtools ? libyui-buildtools seems unused. How does code make way from Git to the OBS and the distro? I think the canonical way is described in the internal Jenkins server only, where it is basically: git clone make -f Makefile.cvs make srcpackage osc ci to devel:libraries:libyui During Hack Week 10 we tried to document the process for YaST at https://en.opensuse.org/openSUSE:YaST_development , https://en.opensuse.org/openSUSE:YaST:_Development_Workflow . Is there something similar for libyui? It is great to see Jenkins being replaced by humans on this list :) -- Martin Vidner, Cloud & Systems Management Team http://en.opensuse.org/User:Mvidner Kuracke oddeleni v restauraci je jako fekalni oddeleni v bazenu

Problem in displaying GUI after "deleteChildren()"
by Ivan Ovcherenko 17 Oct '13

17 Oct '13

Hello I’m issue some troubles with libyui. I’m build up some ui, clear part of it using «deleteChildren()» method of one of my widgets and build another part of ui down from this widget. At first I have good working ui, but after above actions no any ui displayed. I’m check it on openSUSE 12.3 official and custom build libyui 3.0.10 with Qt and NCurses interface plugins - all the same. But with gtk interface plugin in openSUSE 12.3 all works fine. In some rare cases with same technique I got working interface in ncurses but not working Qt. There is a sample code: #include "YUI.h" #include "YWidgetFactory.h" #include "YDialog.h" #include "YLayoutBox.h" #include "YSpacing.h" #include "YLabel.h" #include "YPushButton.h" #include "YEvent.h" #include "YDialogSpy.h" int main(int argc, char **argv) { /*****************************************************************************************/ auto mainDialog = YUI::widgetFactory()->createMainDialog(); auto mainVBox = YUI::widgetFactory()->createVBox(mainDialog); auto mainLabel = YUI::widgetFactory()->createLabel(mainVBox, "Hello world!"); YUI::widgetFactory()->createVSpacing(mainVBox); auto mainButton = YUI::widgetFactory()->createPushButton(mainVBox, "Close"); mainDialog->pollEvent(); YDialogSpy::showDialogSpy(); while (true) { auto event = mainDialog->waitForEvent(); if (event) if (event->eventType() == YEvent::CancelEvent || event->widget() == mainButton) break; } mainDialog->deleteChildren(); /*****************************************************************************************/ mainVBox = YUI::widgetFactory()->createVBox(mainDialog); mainLabel = YUI::widgetFactory()->createLabel(mainVBox, "Hello world #2!"); YUI::widgetFactory()->createVSpacing(mainVBox); mainButton = YUI::widgetFactory()->createPushButton(mainVBox, "Close #2"); mainDialog->pollEvent(); YDialogSpy::showDialogSpy(); while (true) { auto event = mainDialog->waitForEvent(); if (event) if (event->eventType() == YEvent::CancelEvent || event->widget() == mainButton) break; } mainDialog->destroy(); return 0; } -- To unsubscribe, e-mail: libyui-devel+unsubscribe(a)opensuse.org To contact the owner, e-mail: libyui-devel+owner(a)opensuse.org

How to change alignment
by Ivan Ovcherenko 12 Sep '13

12 Sep '13

Hi I need to change an alignment type of YAlignment widget. I know the way, when I can rebuild all interface down from YReplacePoint, that pointed before YAlignment widget, buy with very complex dynamically builded interface it is a very hard work. I'm try to exchange YAlignment widget in widget tree, using add/delete/removeChild(ren) functions, but in the best case I get wrong alignment and broken interface, and segfault in the worst (Because children, "after align" widgets, are deleted, even though that not are children of widget, on what I apply "deleteChildren"). Is there a proper way to change alignment type of YAlignment widget? Or, maybe easiest way is creating changeable alignment widget in libyui?

libyui plugin extensions
by Angelo Naselli 04 Sep '13

04 Sep '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, as someone of you already knows, I'm working in my spare time to libyui plugin extensions. I have something working already really, but I'm not happy enough for asking for a push :) Maybe later we could talk about my implementation and find a good naming convention, class names etc. Anyway I developed a little test case, a general plugin (yes the checkable table i needed :) ) and just a QT specialization atm, that works in the same way as libyui does with its specializations. Unfortunately i had to link manually libyui-qt, that i need to avoid code duplication. I tried changing PROJECTINFO.cmake variables like INTERNAL_DEPS and LIB_LINKER, first failed asking for a find libyui-qt macro missing, latter could not find libyui-qt cause of its position (/usr/lib[64]/yui) but variables were filled corretly, just ld failed. Since into PROJECTINFO.cmake is writtent SET( INTERNAL_DEPS Libyui ) # include libyui or it's plugins (if needed), too! how can i link plugins?

YTable and checkable columns
by Angelo Naselli 18 Jun '13

18 Jun '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, Following Michael ideas I'm trying to summarize what I'm currently discussing with YUI team. I've recently started a new fork to add checkable columns to Ytable. My first will is to got a new rpm front-end in mageia, so the checkable column is intended as rpm installed or, as soon as user checks it, to be installed. Of course un-checking it means to be uninistall :) In the very first implementation i thought to NCTable multiselection, but that imo does not cover the aim. Selecting more lines, means doing something on the selection, which action could finish soon after it's been called -think to a context menu with some actions like print, send via mail etc.-, but even check them all. While checking them means doing something after you selected the one you wanted, where ever they are in the list, not only on the screen (yes i know ctrl + mouse click, but it's not that easy after all, no? :) ), let's say to install/uninstall them for instance in my case. Well to make the long story short, i studied the code a bit and i left the user (well the developer really) decide where and how many chackable columns to put. When a column is checked, an YItem value changed is emitted. Which is the problem then? - - We are trying to understand if we have regressions. - - We are trying to understand if all i did was necessary - - I have a problem in ncurses in which last column sometimes is not shown in its whole - - Thomas does not like how i selected the column in ncurses I think it's all. My code is here https://github.com/anaselli (i need to merge to the last changes though).

YTable notify() and immediateMode()
by Angelo Naselli 15 Jun '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Back on this subject :) Il 10/06/2013 10:09, Gabriele Mohr ha scritto:> Change below would break usage in yast disk: > > diff --git a/src/NCTable.cc b/src/NCTable.cc > > @@ -543,7 +587,7 @@ NCursesEvent NCTable::wHandleInput( wint_t key > ) else { toggleCurrentItem(); - if ( notify() && > immediateMode() ) + if ( notify() || > immediateMode() ) > > -> breaks 'yast disk' module/volume management (when adding a > volume group and selecting a device). { return > NCursesEvent::ValueChanged; } You say that yast disk is broken there, but i cannot see why :( First you introduced a new event there so i believe you changed yast disk behavior also. Second i'm looking comments and code of YTable /** * Deliver even more events than with notify() set. * * With "notify" alone, a table widget sends an ActivatedEvent when the * user double-clicks an item or presses the "space" key on it. It does * not send an event when the user just sends another item. * * With "immediate", it also sends a SelectionChangedEvent when the user * selects another item. "immediate" implicitly includes "notify". **/ bool immediateMode() const; Nothing says ValueChanged, and nothing says that SelectionChange cannot be for one more item. But what i cannot understand really is: "immediate" implicitly includes "notify And the code supports that: void YTable::setImmediateMode( bool immediateMode ) { priv->immediateMode = immediateMode; if ( immediateMode ) setNotify( true ); } It smells like a bug in NCTable implementation to me because ( notify() && immediateMode() ) and immediateMode() are the same clause. That's why i set an || clause, to get both... but reading the comment better i think i cannot return SelectionChanged || Activated when we have both e.g. immediateMode() is true (... it also sends a SelectionChanged...).

libyui-gtk: build fails on gtk3-devel >= 3.9.0
by Björn Esser 16 May '13

16 May '13

Hello libyui-devel-staff! When building on Fedora rawhide (gtk3-devel >= 3.9.0) build fails: src/ygtksteps.c: error: 'gtk_widget_modify_fg' is deprecated (declared at /usr/include/gtk-3.0/gtk/deprecated/gtkstyle.h:678): Use 'gtk_widget_override_color' instead [-Werror=deprecated-declarations] There are some more warnings about deprecated functions. Full build logs are attached. quick fix: cmake -DENABLE_WERROR=OFF I think this can be fixed by updating the affected function-calls BEFORE you'll encounter this on openSuse Factory. cu, Björn

Off Topic: What about dragging the discussion to libyui-devel?
by Michael Andres 16 May '13

It's just because my mailer has no more columns left to indent this thread :) As Hudson no longer floods libyui-devel with 'useless' messages, there's room for serious discussion.
