Displaying QMap objects in a dialog
by Leslie Turriff 06 Dec '16

06 Dec '16

The application I'm writing will have a small group of key-value pairs associated with each object. Looking through the docs, I see widgets for displaying elementary items (e.g. TQListBox), but nothing for something like a TQMap (e.g. a TQlistBoxMap). I could use a TQTable, but that strikes me as akin to using a sledgehammer to kill flies. As a neophite c++ programmer, I know that in theory I can subclass TQListBoxItem to do this, but how to go about that, I haven't a clue. The docs say merely that ' If you need to insert customized items into a TQListBox you must inherit this class and reimplement paint(), height() and width().' Any suggestions to help get me started with this would be appreciated. Leslie

Struggling with "C++ GUI Programming with Qt 3"
by Leslie Turriff 06 Dec '16

06 Dec '16

Hi, I'm trying to learn to write a GUI app using the book "C++ GUI Programming with Qt 3", which of course is not written with Trinity in mind, but hopefully will be enough to get me started. I've already figured out that I need to substitute 'tqmake' for 'qmake', but I can't get the simple 'helloworld' project to actually compile the c++ code. I've got the project generated, and I see the code in its src/ directory, but when I try to build it (the book says to use 'make') it says "make: Nothing to be done for 'first'." Here is the Makefile generated by tqmake: > > ########################################################################### > Makefile for building: Tutorial1 > Generated by qmake (1.07a) (TQt 3.5.0) on: Wed Nov 16 22:57:35 2016 > Project: Tutorial1.pro > Template: subdirs > Command: $(QMAKE) -o Makefile Tutorial1.pro > ########################################################################### > > MAKEFILE = Makefile > MAKE = tqmake > DEL_FILE = rm -f > CHK_DIR_EXISTS= test -d > MKDIR = mkdir -p > INSTALL_FILE= > INSTALL_DIR = > SUBTARGETS = > > first: all > > all: Makefile $(SUBTARGETS) > > Makefile: Tutorial1.pro /usr/share/tqt3/mkspecs/default/qmake.conf > $(QMAKE) -o Makefile Tutorial1.pro > qmake: qmake_all > @$(QMAKE) -o Makefile Tutorial1.pro > > all qmake_all distclean uicables mocables install_subdirs uninstall_subdirs uiclean mocclean lexclean yaccclean clean : FORCE > install: install_subdirs > > uninstall: uninstall_subdirs > > FORCE: > And here is the Project file: > ###################################################################### > # Automatically generated by qmake (1.07a) Wed Nov 16 22:47:58 2016 > ###################################################################### > > TEMPLATE = subdirs > > # Directories Are there additional steps required when compiling a QT project in Trinity?

Hi Guys, PcLinuxOs, Trinity 14, I think I might have stumbled on a bug ! I've had folders seem to disappear when moved from one window to another. I've found that if there are more folders than can be displayed in the window, moving down to the bottom of the window so that the top folders cannot be seen, and then moving a folder from another window into the white space, results in the moved folder disappearing. Doing a find tells me that the missing folder is now in one of the folders above and not in the white space where I put it or in the sort order. If I move to the top of a folder with files below the bottom and If I move and put a folder from another window at the top but between the others it goes where I put it. It works as expected. I can repeat this every time. Note the folder sort is set to "By Name" I mention this because I thought that "Sort" might have something to do with it, but it doesn't seem to. Thanks Guys. -- Best Regards: Baron

Thank you! Inspired by your scripts and the output of xrandr, two lines in my .bashrc did the job: xrandr --output HDMI-0 --right-of DVI-0 --auto --primary xrandr --output DVI-0 --auto I over-simplified the commands because I am on a desktop and my two screens are always connected. No more fiddling with screen settings on each login! :-) On 16-12-01 03:00 PM, deloptes wrote: > iadest(a)o2.pl wrote: > >> OK, this is a sum of 3 scripts I use: >> >> #!/bin/bash >> >> #Test if we are not in dock >> if [ -a /dev/video0 ] >> then >> #echo "Going to dock mode!"; >> xrandr --output LVDS1 --off >> #xrandr --output VGA1 --mode 1600x1200 >> xrandr --newmode "1600x1200b" 180.0 1600 1604 1796 2050 1200 >> 1201 1204 1250 +hsync +vsync >> xrandr --addmode VGA1 1600x1200b >> xrandr --output VGA1 --primary --mode 1600x1200b >> xrandr --addmode DVI1 1600x1200b >> xrandr --output DVI1 --mode 1600x1200b >> xrandr --output DVI1 --right-of VGA1 >> else >> #we are not in dock.

Dual screen setup not remembered
by midi-pascal 01 Dec '16

01 Dec '16

Hi, I use Trinity R14.0.4 under Ubuntu 14.04 on a Dell Optiplex 990. My setup is dual screen (1 HDMI 27po, 1 DisplayPort 24 po) connected to a Radeon video card. The 24po is on my left and the 27po is in front (main screen). I tried tderandrtray, Trinity Control Center, System Settings to set things up with success. But each time I log out or reboot, the display settings are lost. Both screens show the same display (main) and are in reverse order (left/right). Is there a way to make Trinity remember my screen settings so I do not have to set things up each time? Thanks!

Struggling with (T)QT3 tutorial
by gregory guy 27 Nov '16

27 Nov '16

Hi there! Not sure if It"s the right thing to do, but I adjusted tutorial 1 code (hello world) like this: ------------------------------------------------------------- #include <tqapplication.h> #include <tqpushbutton.h> int main( int argc, char **argv ) { TQApplication a( argc, argv ); TQPushButton hello( "Hello world!", 0 ); hello.resize( 100, 30 ); a.setMainWidget( &hello ); hello.show(); return a.exec(); } ------------------------------------------------------------ Since I've compiled Trinity by myself the headers are located in /usr/include/tqt and /usr/include/tqt3, the libraries (all of them) in /usr/lib64. I had to adjust the Makefile file accordingly, like this: --------------------------------------------------------------------------------------------------------------------- INCPATH = -I/usr/share/tqt3/mkspecs/default -I. -I/usr/include/tqt -I/usr/include/tqt3 LINK = g++ LFLAGS = -luuid -Wl,-rpath,/usr/lib64 LIBS = $(SUBLIBS) -L/usr/lib64 -L/usr/X11R6/lib -luuid -ltqt-mt -lXext -lX11 -lm -lpthread --------------------------------------------------------------------------------------------------------------------- Hope that help!

KolourPaint crashes TDE, Kuickshow shows garbage
by J. Drahun 18 Nov '16

Good day, all. So, subj is the problem. 1. (KolourPaint) I just wonder if I'm alone excepting such kind of error. If I'm not, is there any kind of solution? If I'm, I suppose I should file an issue? 2. (Kuickshow) I don't know what happens and if I'm able to do anything, but here's the attachment. I hope it shows.
