cvuchener / dfhack-qt Goto Github PK

Hi
Tried your plugin. Compiled and installed

But it says QApplication not started.
stderr.log and stdout.log don't say anything interesting.

Is there a way to debug this?.
I'm really, really interested in make this work

I got the error below while compiling: https://github.com/ragundo/DwarfExplorer
Reference: ragundo/DwarfExplorer#1

I got this error while compiling with cmake (v 3.10.2, Linux):

CMake Error at plugins/DwarfExplorer/dfhack-qt/CMakeLists.txt:4 (target_include_directories):
  Cannot specify include directories for imported target "dfhack-qt-common".

Was an error with the https://github.com/cvuchener/dfhack-qt/blob/58225d74672e1f870cc9b23c8a4c747900d7f3df/CMakeLists.txt file:

target_include_directories(dfhack-qt-common INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}/include)

gave that error. But fixed it with some searching and changing it to this line:

set_property(TARGET dfhack-qt-common APPEND PROPERTY INTERFACE_INCLUDE_DIRECTORIES
  $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/include>
  )

Also one small compile warning:

../plugins/DwarfExplorer/dfhack-qt/qapplication/LogFilterProxyModel.cpp:104:33: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
     if (ok && type >= 0 && type < accepted_types.size() && !accepted_types[type])
                            ~~~~~^~~~~~~~~~~~~~~~~~~~~~~

Hi there.

Short story.For my plugin, I need to hook up on DFHack onpluginupdate signal.

Long history. I want to change the Dwarf Fortress window to a specific coordinate every time the user selects a structure that contains a df::coord field.
If you call the dfhack methods to do that, it will not work because a CoreSuspender is already active, so the call doesn't have any effect until the CoreSuspender is resumed and the render thread updates the screen.

I've tried to call the dfhack methods, resume the CoreSuspender and sleep my thread a few milliseconds for render to update. Then I suspend again. This sometimes work, sometimes crashes.
The solution is to set the parameters, resume the CoreSuspender and use onpluginupdate to do the work

The problem is that this signal should be implemented in your main.cpp (where the Qt application is created), but I can't figure out how to implement that method using data from my plugin.
I tried to use global variables, but the linker complains.

How to do that?. Is it possible to implement some signal slot between your main.cpp and my plugin?

Thanks in advance

Working beautifully.

I need to do a lot of testing and try it in Windows, but this is promising.

Thanks for your work

Hi.
Right now I can deploy my plugin dwarfexplorer in windows.

Now, I'm trying to do the same in linux (Ubuntu 18.04).The machine is not a development machine, just a clean ubuntu virtual machine.
I downloaded the LNP for linux, Dwarf Fortress and dfhack works ok.

Now, I put the compiled plugins (your qapplication.plugin.so and my dwarfexplorer.plugin.so) in the plugins directory of dfhack.
I run dfhack, and logically dfhack doesn't load the plugins because is missing the required Qt5 libraries.

I know that linux doesn't work like windows. Even if you put the required .so files and the platforms Qt5 directory in the same directory as Dwarf Fortress, it will not work because of the rpath.

Fortunatelly, dfhack in linux is launched by a script that sets LD_LIBRARY_PATH, so, if you put the Qt5 libraries in the directory libs of Dwarf Fortress, dfhack can load boths plugins.

The problem is that as soon as I type enable qapplication, dfhack crashes with a core dump.

I was thinking that the problem is with the platforms Qt directory, so I put a copy of the directory in several places (hack/libs libs etc with no luck. I always get a core dump.

Have you tried to deploy your plugin in a linux machine?. What can I do?.

PD: Of course, in my development machine everything works.

Hi again

I'd like to use QML for my next project.
Do you think that is possible?.
I've tried to use QQuickWidget inside a QMainWindow but without success.

I'd like to have one solution that would be the same for all dfhat-qt plugins

Thanks in advance

Windows 10 - Qt 5.12.3
using qt5_add_resources works !!

There's hope that DFHack maintainer lethosor would try qapplications in MacOS as you requested in the forums.
As last resort , I have a MacOS VM, but my knowledge of Macs is zero :(. Anyway I could try it.

Again, thanks for your wonderful framework!.
