Why i can't change color of QString?

[Engelard]

@VRonin of course i did that. Still same 4 errors

[VRonin]

let's do it manually then: remove all the MODELUTILITIES_EXPORT

[Engelard]

@VRonin said in Why i can't change color of QString?:

MODELUTILITIES_EXPORT

How? you mean edit your src files?

[VRonin]

yep!
All DEFINES += MODELUTILITIES_STATIC does is transforming MODELUTILITIES_EXPORT into an empty string. if that doesn't work then just manually do a find and replace

[Engelard]

@VRonin oKay. In what files that stuff which i should to replace? I only can assume that such stuff MODELUTILITIES_EXPORT is macro, so it must be in some .h files, right?

[VRonin]

Actually, it probably just easier to replace the entire modelutilities_global.h with

#ifndef modelutilities_global_h__
#define modelutilities_global_h__
#define MODELUTILITIES_EXPORT
#endif // modelutilities_global_h__

[Engelard]

@VRonin Done. But still that four errors(

Hi,

Do you mean the symbol missing error ?

Did you build @VRonin library statically ?

I tried multiple times: Build>Clean all>Run qmake>Rebuild all.

[SGaist]

Do you have a .dll file matching that library ?

[Engelard]

@SGaist What .dll? I just downloaded src folder, did'nt saw any dll in there

[SGaist]

The .dll if you have built @VRonin's library.

Otherwise, how did you integrate it in your application ?

Just included rolemaskproxymodel.h and start using that stuff what he showed in example

[mrjj]

@Engelard
Also the .cpp files , i hope ?

There's a section in the readme that explains how to use the library: https://github.com/VSRonin/QtModelUtilities/tree/dev#installation

And it states:

if you use qmake (Qt Creator), you can include the entire source of the library directly in your code by adding include(path/to/source/modelutilities.pri) in your .pro file.

[Engelard]

@VRonin Done. It compiles. But it seems like proxyModel eventually empty. tempBx - is pointer to existed ComboBox:

QStringListModel *tempStrMod = new QStringListModel(personalList);
RoleMaskProxyModel proxyModel;
proxyModel.setSourceModel(tempStrMod);
tempBx->setModel(&proxyModel);

But if i'd change ->setModel to tempStrMod it works.

[VRonin]

You are creating the proxy model on the stack. it is most likely going out of scope.

QStringListModel *tempStrMod = new QStringListModel(personalList);
RoleMaskProxyModel* proxyModel =new RoleMaskProxyModel(personalList);
proxyModel->setSourceModel(tempStrMod);
tempBx->setModel(proxyModel);

[Engelard]

@VRonin Yep. Btw in constructor should be placed temporyStringListModel, what i did. And it does'nt change color of ComboBox mainWidget, only in list(as before with that example where was QStandaradItem), and after like... third use of my function(which create that proxy model), it crashed with that window:

[SGaist]

Hi,

Why are you re-creating your models every time ?

You could just update the content of the QStringListModel rather that recreate everything each time.

[Engelard]

@SGaist replaced all to the constructor. Nothing changed. I understand that @VRonin libraries should grant the possibility to have any Roles on any kind of objects. That's nice feature, will use it in some future maybe. But problem of this topic( i just now realised) - that Qt itself can not change colors of a text of ComboBoxes. Yet.
