dhtml18: My system OS is Window 7, 64bits. I said, I download and installed Qt SDK version 5.5.1 open source distribution from Qt official site. I download Qt 5.5.1 for Windows 32-bit (MinGW 4.9.2, 1.0 GB) first and installed (this is offline installation). when I run the qt creator, it display a blank window form as shown by the screen shots. It uninstall the SDK and reinstalled it the second time assuming the first did not install properly. But the qt creator still display as a blank window form. I installed a fresh one online using the online file (Qt Online Installer for Windows (16 MB)). Which did the installation online following the default setting. the online installer installed Qt 5.5 for Windows 64-bit (VS 2013, 823 MB) and Qt 5.4 for Windows 64-bit (VS 2013, 823 MB) with the qt creator. But when I opened the qt creator it still show blank window form. But the Qt designer, Qt Assistant and Qt Linguist all open with content. screen shots.

all these programming tools are easier to install on Linux than windows, i too had several issues using windows for pyside development....just make the switch (you won't regret it) |
Re: "Qt Creator" Need Solution by BlueMagnificent(m): 3:32pm On Mar 18, 2016 |
Quite an interesting problem cos mine ran straight from the box after installation. My system is Win7 64bit and QtCreator is my ide of choice for coding both qt and non-qt projects. How do you start it up? Having you tried starting it up directly from the executable in the installation directory |
Re: "Qt Creator" Need Solution by ijeezlux(m): 7:56pm On Mar 18, 2016 |
BlueMagnificent: its being a while i heard from this guy(bluemagnificient)... it was your trend you created about Qt that really made meand inspired me to switch over to c++ gui programming. in fact i first heard about Qt in one of your trend. you are too much. just wish i could chat with you on other platform. all the same kudos to you and codemarshal |
Re: "Qt Creator" Need Solution by ijeezlux(m): 8:08pm On Mar 18, 2016 |
hello gurus i have a little issue i need you guys to help me clarify ...... it goes like this.. when writing or reading data into qdatastream object, is it a must that i set the version of the Qt am using e.g (Qdatastream stream; stream.setVersion(...); ). i also have another question. i always see a certain quint32 magic_number variable when doing data serialization with Qdatastream object. but i dont really know whats the main function of this magic_number variable. is it a must to use it? it making me confused...... thanks in advance for ur answer |
Re: "Qt Creator" Need Solution by codemarshal08(m): 5:20am On Mar 19, 2016 |
ijeezlux:Bro have you read through this ? http://doc.qt.io/qt-4.8/qdatastream.html#details |
Re: "Qt Creator" Need Solution by ijeezlux(m): 9:41am On Mar 19, 2016 |
codemarshal08:thanks my main but i still have some things disturbing me |
Re: "Qt Creator" Need Solution by ijeezlux(m): 9:49am On Mar 19, 2016 |
what if the qint32 value read from the qdatastream to the qint32 version variable is not 123.... what will happen |
Re: "Qt Creator" Need Solution by BlueMagnificent(m): 10:04am On Mar 19, 2016 |
Its so unfortunate that we are temporarily hijacking this thread ![]() Quoting from the link posted by codemarshal08
I believe from the doc it is only the storage and retrieval of complex types that might vary with version, basic datatypes are not affected by this @bestiyke, have you been able to resolve your QtCreator issue |
Re: "Qt Creator" Need Solution by ijeezlux(m): 10:17am On Mar 19, 2016 |
BlueMagnificent: can you please name some of the complex data types that may vary with version |
Re: "Qt Creator" Need Solution by BlueMagnificent(m): 10:38am On Mar 19, 2016 |
For complex types I quote from the link again If you are producing a new binary data format, such as a file format for documents created by your application and most probably any custom Datatype of yours like class objects, e.g, layers, filters and brush for an image editing application |
Re: "Qt Creator" Need Solution by codemarshal08(m): 10:46am On Mar 19, 2016 |
ijeezlux: Hmm, Complex types == !buitIn types |
Re: "Qt Creator" Need Solution by ijeezlux(m): 6:32pm On Mar 20, 2016 |
Which one of the following will declare a pointer to an integer at address 0x200 in memory? 1. int *x; *x = 0x200 2. int *x = &0x200; 3. int *x = *0x200; 4. int *x = 0x200; |
Re: "Qt Creator" Need Solution by BlueMagnificent(m): 8:23pm On Mar 20, 2016 |
ijeezlux: Number 2 and 3 are syntax errors. Number 1 assigns the value 0x200 to the int variable pointed to, while number 4 assignes the value of the pointer to be 0x200, in order words the address pointed to. So definitely number 4. Unless you know what you are doing, it is advisable not to assign memory addresses like this |
Re: "Qt Creator" Need Solution by bestiyke(m): 8:54pm On Mar 20, 2016 |
BlueMagnificent:No permenent solution, but I have to run and close it many times for it to open properly. I have been using it. Thanks. If there is any solution I will appreciate. |
