Object Inherit from QTreeWidgetItem

[xgoan]

Hi,

i'm making a QTreeWidget that uses an object that inherits from QTreeWidgetItem.

the code is:
Object.h

#pragma once
 
#include <QPixmap>
#include <QDir>
#include <QFile>
#include <QString>
#include <QTreeWidgetItem>
 
#include "Resources.h"
 
class Object:public QTreeWidgetItem{
    public:
        Object(QString file="",QString fileInfo="");
        void init();
 
        bool isObject(){return (m_pixmap!=NULL);};
        void setName(QString newValue);
        void setPixmap(QString file=RES_FOLDER_22x22);
    private:
        QPixmap *m_pixmap;
        QString m_name;
        QString m_file;
        QString m_fileInfo;
};

#pragma once

#include <QPixmap>
#include <QDir>
#include <QFile>
#include <QString>
#include <QTreeWidgetItem>

#include "Resources.h"

class Object:public QTreeWidgetItem{
    public:
        Object(QString file="",QString fileInfo="");
        void init();

        bool isObject(){return (m_pixmap!=NULL);};
        void setName(QString newValue);
        void setPixmap(QString file=RES_FOLDER_22x22);
    private:
        QPixmap *m_pixmap;
        QString m_name;
        QString m_file;
        QString m_fileInfo;
};

Object.cpp

#include "Object.h"
 
Object::Object(QString file,QString fileInfo):m_file(file),m_fileInfo(fileInfo){
    m_pixmap=NULL;
    init();
}
 
void Object::init(){
    if(QFileInfo(m_file).isDir()){
        QDir dir(m_file);
        setName(dir.dirName());
        setPixmap();
        foreach(QString entry, dir.entryList(QDir::Dirs|QDir::NoDotAndDotDot)){
            Object *newObject;
            addChild(newObject);
            newObject=new Object(m_file+"/"+entry);
        }
    }
    else{
 
    }
}
 
void Object::setName(QString newValue){
    m_name=newValue;
    setText(0,newValue);
}
 
void Object::setPixmap(QString file){
    if(QFile(file).exists()){
        if(m_pixmap) delete m_pixmap;
        m_pixmap=new QPixmap(file);
        setIcon(0,QIcon(file));
    }
}

#include "Object.h"

Object::Object(QString file,QString fileInfo):m_file(file),m_fileInfo(fileInfo){
    m_pixmap=NULL;
    init();
}

void Object::init(){
    if(QFileInfo(m_file).isDir()){
        QDir dir(m_file);
        setName(dir.dirName());
        setPixmap();
        foreach(QString entry, dir.entryList(QDir::Dirs|QDir::NoDotAndDotDot)){
            Object *newObject;
            addChild(newObject);
            newObject=new Object(m_file+"/"+entry);
        }
    }
    else{

    }
}

void Object::setName(QString newValue){
    m_name=newValue;
    setText(0,newValue);
}

void Object::setPixmap(QString file){
    if(QFile(file).exists()){
        if(m_pixmap) delete m_pixmap;
        m_pixmap=new QPixmap(file);
        setIcon(0,QIcon(file));
    }
}

and the function that fills the QTreeWidget

void Objects::refreshFiles(){
    QString objectsPath=OBJECTS_PATH;
    QDir dirInfo(objectsPath);
    if(dirInfo.exists()){
        foreach(QString entry, dirInfo.entryList(QDir::Dirs|QDir::NoDotAndDotDot)){
            Object *item=new Object(dirInfo.absolutePath()+"/"+entry);
            treeObjects->addTopLevelItem(item);
        }
    }
}

void Objects::refreshFiles(){
    QString objectsPath=OBJECTS_PATH;
    QDir dirInfo(objectsPath);
    if(dirInfo.exists()){
        foreach(QString entry, dirInfo.entryList(QDir::Dirs|QDir::NoDotAndDotDot)){
            Object *item=new Object(dirInfo.absolutePath()+"/"+entry);
            treeObjects->addTopLevelItem(item);
        }
    }
}

for the TopLevelItems it works fine, but in subitems it uses the first top level item again.

Any ideas. Thanks

for the TopLevelItems it works fine, but in subitems it uses the first top level item again.

As far as I remember, there's some restriction in QTreeWidget code that one can not construct a tree of items first and then add the top level item. One might need to add the top level item first and then continue with adding child items.. I didn't read through your code carefully though so I'm not sure if that's the case.

You might consider using QDirModel+QTreeView too, it might simplify things quite a lot.. take a look at this post.

Ouch...

So I will do the recursivity in the refreshFile() function.

Thanks for the help.

Another question, can the QTreeWidget items be resized?

[jpn]

Try QTreeWidgetItem::setSizeHint

[xgoan]

Could be, but the icon dont resize properly because the item has the same space between QIcon and Text

[jpn]

How about QAbstractItemView::setIconSize?
