[Interest] QuickFrameBufferObject does not redraw

Hi everybody, I am currently experimenting with the QFrameBufferObject and try to draw via raw OpenGL calls. The relevant part of the render function in the QuickFrameBuffrObject::Renderer looks like this: void Drawer::render() { int width = 1.0f; int height = 1.0f;

Re: [Interest] QuickFrameBufferObject does not redraw

Hi, You most likely have some state set that affects your custom rendering. For example you will probably have a program active which is not ideal in your case. Try adding a glUseProgram(0). See the slightly enhanced 5.5 docs at

Hi, I hate to ask, but I can't seem to understand while building Qt 5.5.0 on linux why the 1st command fails and the 2nd succeeds: 1%> (cd /opt/local/build/qtbase/src/plugins/sqldrivers/sqlite ; g++ -v -L/opt/local/lib -O3 -march=native -fpermissive -g -Wl,--no-undefined

[Interest] QtCanvas3D + three.js + OBJMTL

Hi, QtCanvas3D is cool, the demos are fine in Qt 5.5! However, looking at the code, I miss some features regarding three.js-support: 1) is QtCanvas3D supporting only ThreeJSLoader, or could I also use OBJLoader+MTLLoader (=OBJMTLLoader)? Are demos available for this use case? 2) the

[Interest] Using Qt as backend for plugin to be loaded on a host software

Hi. I’m developing a plugin to be loaded by a music software host (VST). There are some lighter alternatives to provide graphics, network and other kinds of useful resources but I want to use Qt. I simply Love Qt! When the plugin is open by the host, it provides a window ref to the plugin. On

[Interest] Qml javascript super keyword

Hi, anybody know if there's a way to have the *super* keyword (ES6 specification) equivalent into a qml script? I have seen the signal workaround (see link below), but sadly this does not get reevaluated like functions parameters, it only get called once which is not correct with what I want to

[Interest] Why das rcc -list my.qrc appen CRCRLF ?

Hi, Why das rcc -list my.qrc append CRCRLF to line end?   I have cmake code ( from QtCompanies quickcompiler ) which does a \n to ; replace to convert a string to a cmake list   and iterates over the elements. That did not work because the guy who wrote that is not aware of windows. I tried

Hi Konstantin, Yes! I have been told before. I think the solution for that particular case is to namespace the build. Haven’t tried yet. I want to sort this problems first. Thanks for warning me. Regards, Nuno > On 16 Sep 2015, at 19:01, Konstantin Tokarev wrote: > > I

Hi, After spending the whole day around Carbon and HIToolbox I’m now sure that the WindowRef provided is a for a Carbon window. However I’m not been able to add a single colored NSView to the windows provided by the host. This what I have been trying to do. Is there anyone with experience in

Sze, That’s awesome news! :) I’m still struggling making the QQuickView being displayed on the window given by the host. In my case I really need to draw the Qt content on the window provided by the host, otherwise the behaviour is awkward. I will let you know when I have this working. Nuno

[Interest] Bug in QPlainTextEdit::find

Currently, if you set the flags to QTextDocument::FindWholeWords The system ONLY checks for a boundary of isNumberOrLetter, which is NOT the same as a whole word. For instance, if you are searching for the whole word "state" and the text is "current_state" is should NOT match, however it does,
