How to compile QT windows for use in the Edtior?

waf_files have those 3 files included.

Hmm what does the include look like? It should probably be something like:

#include "Editor/ui/ui_alternativeaudiohelper.h"

Maybe the path is not correct?

Thanks!

Hello @REDACTEDUSER

What does you .waf_files look like? It needs to include three files:

.h

.cpp

.ui

An example to take a look at would be dev/Gems/ScriptCanvas/Code/Editor/View/Dialogs/NewGraphDialog.cpp (h, ui)

Hope that helps,

Thanks!

Same thing...

wscript:

    def build(bld):
bld.DefineGem(
# Add custom build options here
includes = [
bld.Path('Code/CryEngine/CryAction')
],
win_features = [
'crcfix'
],
editor = dict(
features = [
'qt5'
],
use = [
'AzToolsFramework',
'AzQtComponents',
'EditorCore',
'EditorUI_QT',
'EditorCommon'
],
includes = [
bld.Path('Code/CryEngine/CryCommon'),
bld.Path('Code/Sandbox'),
bld.Path('Code/Sandbox/Editor'),
bld.Path('Code/Sandbox/Editor/Include'),
bld.Path('Code/Sandbox/Plugins/EditorCommon')
],
uselib =[
'QT5CORE',
'QT5GUI',
'QT5WIDGETS'

defines = [
'AA_EDITOR'

Yes the include path needs to be like I suggested above. What is the error that you get? Try taking a look at the BinTemp folder to see if the ui_alternativeaudiohelper.h is being generated.

Try this: #include "Source/Editor/ui/ui_alternativeaudiohelper.h"

Here's the editor waf_file:

  {
"none": {
"Source": [
]
},
"auto": {
"Editor/Include": [
],
"Editor/Source": [
],
"Editor/Source/Components": [
"Source/Editor/AlternativeAudioEditorSystemComponent.cpp",
"Source/Editor/AlternativeAudioEditorSystemComponent.h"
],
"Editor/Source/UI": [
"Source/Editor/ui/alternativeaudiohelper.ui",
"Source/Editor/ui/alternativeaudiohelper.cpp",
"Source/Editor/ui/alternativeaudiohelper.h"
]
}
}

#include "ui_alternativeaudiohelper.h"

Which, if i manually compile the ui to h, does work.

EDIT: tried "#include <Editor/ui/ui_alternativeaudiohelper.h>", same thing. "Cannot open include file" Is there something in the wscript that i'm missing? Also, even if i do manually compile the ui to h, it gives me linking errors:

Ok, that apparently worked and is giving me the errors listed above about meta fuctions and variables:

LNK2001	unresolved external symbol "public: virtual int __cdecl alternativeaudiohelper::qt_metacall(enum QMetaObject::Call,int,void * *)" (?qt_metacall@alternativeaudiohelper@@UEAAHW4Call@QMetaObject@@HPEAPEAX@Z)

LNK2001	unresolved external symbol "public: virtual void * __cdecl alternativeaudiohelper::qt_metacast(char const *)" (?qt_metacast@alternativeaudiohelper@@UEAAPEAXPEBD@Z)

That probably means it's having linker issues. Try just using uselib and remove autod_uselib. Also you should only need QT5Core, QT5GUI, and QT5Widgets unless you require the other libs somehow. Try also removing the features property.

Let me know what you end up with and what the output looks like. It might require a deeper investigation into why it can't find the symbols.

Thanks

I think i might have found out what's wrong.

The meta stuff is because the waf system isnt generating any moc files which is needed to compile.

I found all of the QT stuff in "BinTemp/<build>/qt" folder and ScriptCanvas generates moc files and .h files for ui's but not for my gem. Wierd...

@REDACTEDUSER

So the issue is that when compiling, moc is suppose to execute on the qt header and source files to generate moc files. apparently it does execute on the script canvas gem and generates moc files but it doesnt execute on my gem. I cant seem to find out why it executes on the script canvas gem but not my gem...
