Right, now I understand. :o) You need to create yourself a QPixmap which allows you to use a QPainter object to draw out the graph and coordinates which you want to display. You can then convert the QPixmap to something like a BMP or JPG which you can display on screen in a window. The interface for doing this sort of thing from Qt is low level, which means complicated and fiddly! If it's possible for your application, you might do better to draw your BMP image using Perl (the GD package comes to mind, but there might be others) then show the image file on screen using Qt. -- > eatapple core dump

Not really! You're a bit vague... If you have an image in BMP format (or almost any other popular format for that matter) you can display it quite easily. Crib some code from the "showimg" example in the qt3-examples package. -- > eatapple core dump

Germany character /Umlaut letter on SuSE 9.1, Qt 3.1.
by Prabu Subroto 26 Aug '04

26 Aug '04

dear my friends... my QTable dan QMessageBox can not display umlaut letter such as ' ä ' (ae), ' ü ' (ue) and ' ö '(oe). My QDataBase and my QLineEdit can display the umlaut letters but the QMessageBox and QTable don't. Here I tried this line... 1. with QMessageBox: int itemsidcomboBox = salesidcomboBox->currentItem(); if (itemsidcomboBox==0){ QMessageBox::warning(this, "Achtung !", "Für welche Berater ID ?" ); return false; } 2. with QTable: liattable->setText(0,0, "äüö"); and both of them can not display the umlaut character (ö,ü. ä) properly. What should I do? what should I do to make my QTable and my QMessageBox can display the umlaut letters. Thank you very much in advance. __________________________________ Do you Yahoo!?

VxWorks to Linux
by expatriate 26 Aug '04

26 Aug '04

Hello VxWorks literati We're considering moving to Linux and one of the questions that was asked is: How do you emulate what's best of the VxWorks shell? In VxWorks, the shell interpreter can call any library function currently loaded and execute it on the spot. For example, one can type at the shell: printf("Val = %d\n",x) and the library function printf will be executed and the current value of x will be searched in the symbol table and passed on to the printf function. Although this is a trivial example, perhaps the intended use would be more appropriate. Suppose a function called "foo(int a, double b)" exists in a shared library used by a currently executing process. Is there an "easy" way to ask the process to search its symbol table and execute foo(a,b) for us? Perhaps there's no easy way and each process now needs some form of IPC glued to it so we can funnel a command into it. Is there a Linux command to get the function pointer from a symbol table search? Am I making any sense? TIA & cheers

libncurses.so not linked in SuSE 9.1?
by Pete 26 Aug '04

26 Aug '04

Hi All, I'm just learning to program using the ncurses library on SuSE9.1. However, it seems that while there are a few versions of the libcurses.so.{x} and libncursesw.so.{x}.{y}...(?) shared objects, there is no established libcurses.so link (like many of the other system libraries). Is this just a minor bug? I'm getting by for now by making a symbolic link to libncursesw.so.5 and it seems to be working alright for my limited needs. Is this correct? Has anyone else experienced this? Thanks, Pete __________________________________ Do you Yahoo!? Read only the mail you want - Yahoo! Mail SpamGuard. http://promotions.yahoo.com/new_mail
