QString class global

[prophet0]

how can i access a QString ill show my code on how im trying to do this

bottom.h

extern QString *buttonFV;

extern QString *buttonFV;

To copy to clipboard, switch view to plain text mode 

then in bottom.cpp

while(iconmodel->query().next())
    {
      buttonFV = iconmodel->query().value(0).toString();  // String I'm Tring to get the value from in a slot
 
        emit next_DoStyle();
 
 
    }

while(iconmodel->query().next())
    {
      buttonFV = iconmodel->query().value(0).toString();  // String I'm Tring to get the value from in a slot

        emit next_DoStyle();


    }

To copy to clipboard, switch view to plain text mode 

SLOT in bottom.cpp

void ttmbottom::do_Style()
{
 
    QString bttnPath;// = QApplication::applicationDirPath();
    bttnPath = "/home/dev/ttm/directory/icon/";
    bttnPath += buttonFV;  // trying to use it here !!!!!
 
 
 
}

void ttmbottom::do_Style()
{

    QString bttnPath;// = QApplication::applicationDirPath();
    bttnPath = "/home/dev/ttm/directory/icon/";
    bttnPath += buttonFV;  // trying to use it here !!!!!



}

To copy to clipboard, switch view to plain text mode 

if anyone can help me solve this issue i always have problems trying to use the data i have stored

Why You don't define slot as

void ttmbottom::do_style(QString);

void ttmbottom::do_style(QString);

To copy to clipboard, switch view to plain text mode 

and then emit signal as

emit next_DoStyle(iconmodel->query().value(0).toString());

emit next_DoStyle(iconmodel->query().value(0).toString());

To copy to clipboard, switch view to plain text mode

Sorry would you be able to show a little example as im testing it with mine and cant seem to get it working

[Lesiok]

First show definition of class ttmbottom. Then I will be able to modify.

The code as presented should not compile. Regardless of which compilation unit contains buttonFV, buttonFV is a pointer to a QString not a QString. Line 2 of the first and line 6 of the second bottom.cpp are trying to use pointer to a QString as if it were a QString.

any work arounds you suggest ?

[ChrisW67]

You cannot "work around" invalid C++ syntax: you just have to correct it. Either make buttonFV an actual QString, or change everything that uses it to expect a pointer to a QString.

ok thanks ill change everything to expect a pointer
