Hi all,

I am writing a console app in Qt for KDE. However I need credentials for a service. For this I want to use KWallet. While I can use the openWallet function if my class is derived from QDialog, I can't use it when I derive from QObject because I can't use the winId() function.

What would be the proper way of doing this?
Do I just have to derive from QDialog (QWidget) and don't use the show() function? Or is there another way to use Kwallets openWallet function with deriving from QObject instead?

Thanks in advance!

According to the API documentation of KWallet::Wallet, it should be possible to do this.
Please see http://api.kde.org/4.8-api/kdelibs-apid ... 7568854a28

In short, just pass 0 instead of a proper window ID.

First of all thank you for helping me out!

I tried with a 0 and with a WId type of variable as well (as that is what winId() returns).

I uploaded a small part of the code that is relevant:

I get the following while running make:

Code: Select all

CMakeFiles/connect-kwallet.dir/connect-kwallet.o: In function `ConnectKwallet':
/home/gvm/projects/connect-kwallet/connect-kwallet.cpp:10: undefined reference to `KWallet::Wallet::NetworkWallet()'

collect2: ld returned 1 exit status
make[2]: *** [connect-kwallet] Error 1
make[1]: *** [CMakeFiles/connect-kwallet.dir/all] Error 2
make: *** [all] Error 2


So this might be a CMakeLists.txt file issue?

Code: Select all

project(connect-kwallet)
cmake_minimum_required(VERSION 2.6)
find_package(KDE4 REQUIRED)

include_directories(${KDE4_INCLUDES} ${KDE4_INCLUDE_DIR} ${QT_INCLUDES} ${CMAKE_CURRENT_BINARY_DIR})

set(connect-kwallet_SRCS connect-kwallet.cpp main.cpp)
qt4_automoc(${connect-kwallet_SRCS})
add_executable(connect-kwallet ${connect-kwallet_SRCS})
target_link_libraries(connect-kwallet ${QT_QTCORE_LIBRARY})


I really hope you can spot the issue!

Just for clarity adding another body...

I fixed it! I was just thinking about that it is a linker error so probably an issue with the librarie settings in the CMakeLists.txt
I compared with another KDE project and changed the last line:

Code: Select all

target_link_libraries(connect-kwallet ${QT_QTCORE_LIBRARY} ${KDE4_KDECORE_LIBS} ${KDE4_KPARTS_LIBS} ${KDE4_KDEUI_LIBS})


Probably I can make this shorter but it might give someone else a clue!

Thanks again!

Looks like you might have an include problem. Do you have the KWallet libraries included into your source code file?

Note that I marked the topic as solved;)
It was indeed a libraries include issue

Thanks anyway for checking out my thread!
