Re: [Interest] Windows VST plugin based on Qt

2015-05-19 Thread Tony Rietwyk
Hi Nuno, I strongly suggest to download Dependency Walker utility, and use that to test loading your DLL on Windows. Also, there are dozens of VST examples available, maybe you start with one that works, then extend it with Qt or whatever. Regards, Tony Sent: Tuesday, 19 May 2015 4:27

[Interest] Windows VST plugin based on Qt

2015-05-19 Thread Nuno Santos
Hi, I’m trying to build a VST plugin based on Qt. A VST plugin is a framework for creating audio processing and instrument plugins. It provides an api that one should follows. The result is a dynamic library that will be loaded by the host (dll on windows case, bundle on mac case). I have

2015-05-19 Thread Kalinowski Maurice
Creating a VST is certainly possible, though you will need to do some extra steps. a) you need an application object created inside your plugin. The easiest to do so is to create a new thread (when the first instance is created or even on show(), not during plugins loading), which will

Maurice, Thanks for your reply. There is certainly a lot to absorve from your answer. But I want to focus on small steps for now. The problem so far in Windows is that when I put the dlls on the VST plugins dir the host is not able to detect it (by host I mean Ableton Live and/or Bitwig for

Is this a bug or am I doing something wrong? qt-5.5 does not compile on 10.8 out of the box. it is probably going to be fixed before the release (afaict, 10.8 is still supported) tim ___ Interest mailing list Interest@qt-project.org

2015-05-19 Thread Constantin Makshin
Doesn't look like a bug to me. The description of QProgressBar::reset() says: The progress bar rewinds and shows no progress. Indeterminate progress bars have no progress/value by definition so there's nothing to reset. I admit that setting a non-zero range just to disable a progress bar looks a

5.5 Beta does support 10.8, at least CI still covers it. The issue must be related with -platform macx-clang-32, that's unsupported for a while. Regards, Liang On 19 May 2015 at 11:58, Tim Blechmann t...@klingt.org wrote: Is this a bug or am I doing something wrong? qt-5.5 does not

Thiago, Thanks for your reply. Yes, this is 5.4. I will investigate this further by doing some output on the waitForFinished return result. I want to avoid installing another toolkit right now (lack of time and lack of space in my laptop) but I will consider it if the problems persists.

I have a progress bar used to show that some task is executing. Some times I know how its actual progress, and sometimes I don't. When the task is done, I call QProgressBar::reset(). This is fine if I know the actual progress (value range is non-empty). When I don't (value range = [0, 0]),

Thiago, I have found the cause. The command binary was not present on the directory thus, every call was being invoked without the program. It never started, it never ended. You were right. It was a zombie attack. Nuno Santos Founder / CEO / CTO www.imaginando.pt +351 91 621 69 62 On 19
