Compile QFileDialog.h

[Qt Coder]

I need to customize QFileDilaog for my application.

(need to disable its "Navigation" functions and "create folder" function)

I had subclassed it and thought I would disable these slots
like this.....

dialog->removeAction(QAction::setDisabled (true)   [_q_navigateBackward]);

dialog->removeAction(QAction::setDisabled (true)   [_q_navigateBackward]);

To copy to clipboard, switch view to plain text mode 

But all the slots are defined as "Private" so not accessible through object of my derived class.


So I changed specifier from "private" to "public" in "D:\Qt\4.4.3\src\gui\dialogs\qfiledialog.h" ,so that I can access it in derived class.

I need to know now ,how to compile this qfiledialog.h file so that my changes would be in effect.

or is there any alternavite way to acheive this??

First of all I don't understand this code:

dialog->removeAction(QAction::setDisabled (true)   [_q_navigateBackward]);

dialog->removeAction(QAction::setDisabled (true)   [_q_navigateBackward]);

To copy to clipboard, switch view to plain text mode 

And second of all, as I remember from another topic you want to let the user choose the file from some directory, which directory cannot be changed? I think that it would be much easier to just show the some dialog containing some list view (or tree view to have more columns) with files from that directory, and allow user to choose one row and press OK.
You can get files with QDir::entryList().

QDirModel
QTreeView

I have implemented QInputDialog to select images

AppPath = QApplication::applicationDirPath();
      AppPath.append("/Images");
 
       QDir dir = QDir(AppPath);     
       dir.setFilter( QDir::Files | QDir::Hidden | QDir::NoSymLinks );
       dir.setSorting( QDir::Name);
       dir.setNameFilters(filters);
 
       QStringList filenames = dir.entryList(filters,QDir::Files, QDir::Name);
 
       filepath = QInputDialog::getItem(NULL, tr("Select Image"),
                                          "", filenames, 0, false, &ok);

AppPath = QApplication::applicationDirPath();
      AppPath.append("/Images");

       QDir dir = QDir(AppPath);     
       dir.setFilter( QDir::Files | QDir::Hidden | QDir::NoSymLinks );
       dir.setSorting( QDir::Name);
       dir.setNameFilters(filters);

       QStringList filenames = dir.entryList(filters,QDir::Files, QDir::Name);

       filepath = QInputDialog::getItem(NULL, tr("Select Image"),
                                          "", filenames, 0, false, &ok);

To copy to clipboard, switch view to plain text mode 

Now my problem is,even if I click open/cancel /close its returning me the filename selected in combo box.

Is there any way to differentiate between accepted and rejected signal of QInputDialog?

Is there any way to differentiate between accepted and rejected signal of QInputDialog?

Check this:

int returnCode;
returnCode = fileDialog->exec();
if(returnCode == QDialog::Accepted)
   do something.
if(returnCode == QDialog::Rejected)
   do something else.

int returnCode;
returnCode = fileDialog->exec();
if(returnCode == QDialog::Accepted)
   do something.
if(returnCode == QDialog::Rejected)
   do something else.

Its giving me error creating object of QInputDialog.

../../../include/QtGui/../../src/gui/dialogs/qinputdialog.h:70:
QInputDialog::~QInputDialog()' is private

../../../include/QtGui/../../src/gui/dialogs/qinputdialog.h:70:
QInputDialog::~QInputDialog()' is private

To copy to clipboard, switch view to plain text mode 

So I m using

filepath = QInputDialog::getItem(NULL, tr("Select Image"),
                                          "", filenames, 0, false, &ok);

filepath = QInputDialog::getItem(NULL, tr("Select Image"),
                                          "", filenames, 0, false, &ok);

To copy to clipboard, switch view to plain text mode 

but to call

fileDialog->exec();

fileDialog->exec();

To copy to clipboard, switch view to plain text mode 

I will have to instantiate QInputDialog........


How to?

Didnt you read the manual?: http://doc.trolltech.com/4.5/qinputdialog.html#getItem

If ok is nonnull *a ok will be set to true if the user pressed OK and to false if the user pressed Cancel
