Testing examples from the manual in ubuntu 6.10

[chen]

Like Im so interested in Linux version and I have had some problems, I decided
to test most of the examples in the manual.... starting with the "gadget" section

The examples here are not working for me, because I forget something
or simply they dont work.... Im comparing with the windows version.

I have all the flags on : enable debuger, asm support, create unicode executable
create threadsafe executable

Using Ubuntu 6.10, PB 4 beta 2

+++ With Problems +++

Code: Select all

 If OpenWindow(0, 0, 0, 120, 100, "ButtonImage", #PB_Window_SystemMenu | #PB_Window_ScreenCentered) And CreateGadgetList(WindowID(0))
    If LoadImage(0, "/home/chen/pb/pbcomm/Images/PBIDE.bmp")    ; change 2nd parameter to the path/filename of your image
      ButtonImageGadget(0, 10, 10, 100, 83, ImageID(0))
    EndIf
    Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
  EndIf

- does not work in unicode (compiler options: unicode executable).
- does not work with ".ico" images

Hi chen,

first, for other image formats than bmp you have to use the UsexxxImageDecoder() commands... and ico isn't supported(yet) on linux.

the missing constant is worth to report in the bug section

second example works here (it will be a good idea to tell us the used PB-version...) maybe not all needed devel packages installed? (just a guess)

for a new line in the Editorgadget() you'll have to ad a chr(10) to the end of the line...

the Explorerlist doesn't know, where to search... only *.* didn't do the job... try "/*.*" instead...

frame3D ... yes, that depends on the theming engine.... (on my machine there is NO difference)

the Unicode and imageloading... report it (with the linker error) in the Bug-section...

The MDI-Gadget... I guess there is an error too... feel free to report this as a bug... (if you delete the line CreateGadgetList(WindowID(#MDIChild)) it works mostly as expected.... :roll:

the WebGadget,,, take a look at /etc/ ... do you have a ld.so.conf file?
if not, create one (as root) and add the path to firefox (or mozilla) to this file
(i.e. /usr/lib/firefox/ where it's installed on my machine) after that run su ldconfig ..

(it will be a good idea to tell us the used PB-version...)

PB4 Beta 2... Sorry..

Im gonna check out your answers... thanks

Updated in the post.

I reinstalled Ubuntu and is working....

for a new line in the Editorgadget() you'll have to ad a chr(10) to the end of the line...

I know... but something is missing... windows does not require chr(10)

the Explorerlist doesn't know, where to search... only *.* didn't do the job... try "/*.*" instead...

I suppose it must be fixed..... it works as you said.

frame3D ... yes, that depends on the theming engine.... (on my machine there is NO difference)

I changed theme and and dont see any difference... I gonna try other themes..

the WebGadget,,, take a look at /etc/ ... do you have a ld.so.conf file?
if not, create one (as root) and add the path to firefox (or mozilla) to this file
(i.e. /usr/lib/firefox/ where it's installed on my machine) after that run su ldconfig ..

done..... and working

Thanks for your support....

In fact all the exAmples with OpenConsole() dont work

Did you set the compiler options form "linux" to "console"?

[Nik]

Actually Linux doesn't have ONE Terminal emulator, but many different therfore it is not that easy to open one with the OpenConsole Command, it would also be very very very uncommon for a Linux Software to do that. If You use Commandlien Software on Linux you start it from a console, that's it.

No, because I can start cmd-line-apps from X by passing them the option "open in terminal" and what about calling the $TERM Var?
At the moment I can't check (because I gotta use Windoze), but I know that every user can set a Variable for the favorite terminal emu. Same with WWW-BROSWER and som other apps and configs.

Done...it works...

[freak]

We had this discussion allready:

On linux, you have to start the terminal first, then launch the executable inside it. (or both at once with commandline parameters).
You cannot start your exe, and let it open a terminal around it.
Thats why OpenConsole() cannot do this.
