wwWidgets

[wysota]

I'm back now, so I can answer all the questions

Since we are expecting the our private data to be derived from QwwPrivate. Why do the functions like d_func() use reinterpret_cast rather than a dynamic_cast ?

1) Qt works exactly the same way
2) dynamic cast is not needed as the component designer knows the class name, so there is no point of using dynamic cast because you can't access pimpl from outside the class anyway.
3) dynamic_cast relies on RTTI from the compiler, so you'd want to avoid that if possible.

I know you said not to to comment about "unstable" widgets,

That was because some things may not work, so I didn't want to see comments like "X doesn't work" - I already know it doesn't work Any other comments on unstable widgets are welcome.

but I had some minor success yesterday hacking the qwwnavigationbar component into some sort of stability.

The navigation bar is stable, the problem with it is that you can't use its Designer plugin correctly, because of a major bug in Qt.

I've got the primary functionality working with the PushButtons activating the correct QWidget in the top half of the splitter and have sucessfully "styled" the PushButtons to the original "Outlook" (silver version) look similar to my screen grab above but without the minimize bar. The question is if you want the code fed back - I've changed both the header (replacing the topButton with a QLabel) and cpp and have added pngs to the resource file. Any interest?

Sure, let's have a look . I don't think you have to add any images to the resource file, as CSS capabilities from Qt should allow you to make use of external images. About the button in the header - you can access the button and disable its "clicking" functionality if you don't like it without modifying the actual class (or you can subclass of course).

How to install component?
After i build ,i got wwwidgets4.dll and wwwidgets4.lib
i put 2 files into qtdesigner plugin folder but nothing new component load.

You should have run "nmake install" after the compilation. The dll needs to be present in both the lib directory (so that you can make use of the component from your applications) and in the bin directory (so that Designer can access it). Furthermore you should have the file "wwwidgets4plugin.dll" available as well and it should land in your plugins/designer folder (nmake install should take care of that).

On linux this creates a file called libwwwidgets4plugin.a, I was under the impression that the plugins should be *.so files...?

Well... you should have received a .so file if you didn't stick any "static" keywords during preconfiguration. I'll have a look at the project file to see what might have gone wrong and I'll get back to you on that.

The navigation bar is stable, the problem with it is that you can't use its Designer plugin correctly, because of a major bug in Qt.

Unfortunately, when you claimed the widget was unstable it wasn't clear what this meant. When I started testing it I used a test routine like this

#include <QtGui>  
#include <qwwnavigationbar.h>
 
int main(int argc, char ** argv)
{
    QApplication app(argc, argv);
    QMainWindow* win  = new QMainWindow();
    QwwNavigationBar* nav = new QwwNavigationBar(win);
    nav->addWidget(new QFrame(), "First Widget");
    nav->addWidget(new QFrame(), "Second Widget");
    nav->addWidget(new QFrame(), "Third Widget");
    win->setCentralWidget(nav);
    win->show();
    return app.exec();
}

#include <QtGui>  
#include <qwwnavigationbar.h>
  
int main(int argc, char ** argv)
{
    QApplication app(argc, argv);
    QMainWindow* win  = new QMainWindow();
    QwwNavigationBar* nav = new QwwNavigationBar(win);
    nav->addWidget(new QFrame(), "First Widget");
    nav->addWidget(new QFrame(), "Second Widget");
    nav->addWidget(new QFrame(), "Third Widget");
    win->setCentralWidget(nav);
    win->show();
    return app.exec();
}

To copy to clipboard, switch view to plain text mode 

which creates the screen window attached. The text for the second and third widgets was missing. This is when I started hacking . I believe I have a working solution, but as I can't be sure that this matches your original design, I'd rather PM the changes to you.

AFAIR the titles are taken from the "windowTitle" property of widgets added to the bar (that's one of the workarounds for one of Qt Designer problems), so this should work:

QwwNavigationBar* nav = new QwwNavigationBar(win);
QFrame *frm = new QFrame;
frm->setWindowTitle("First widget");
nav->addWidget(frm);
frm = new QFrame;
frm->setWindowTitle("Second widget");
nav->addWidget(frm);
frm = new QFrame;
frm->setWindowTitle("Third widget");
nav->addWidget(frm);

QwwNavigationBar* nav = new QwwNavigationBar(win);
QFrame *frm = new QFrame;
frm->setWindowTitle("First widget");
nav->addWidget(frm);
frm = new QFrame;
frm->setWindowTitle("Second widget");
nav->addWidget(frm);
frm = new QFrame;
frm->setWindowTitle("Third widget");
nav->addWidget(frm);

To copy to clipboard, switch view to plain text mode 

The same goes for windowIcon property and the decoration of the button. I can't be certain the current code works this way (and I can't test it on this computer), but it is the way it was meant to work.

[pdolbey]

Unfortunately that pattern isn't obvious from either the interface description, or from my initial test with only one button that worked "correctly". I could see that window titles were being used in the code, but I didn't realise that these were supposed to be the primary title source, and when I have specified text in my method call I would have expected it to have been displayed. Thats whay I thought the widget was inherenently unstable.

That's why the widget is called "unstable" and the whole release "beta" The interface of the navigation bar will change a bit because some things will be done outside the widget and inside Designer (just like with the task panel). When this is done, the behaviour will be coherent.

[wysota]

Ok, I finally forced myself and published the next, (almost) fully usable beta of wwWidgets.

All comments are of course welcome.

Oh... and of course a screenshot of some of the widgets.

[pdolbey]

Building on Windows, I get

1>.\qwwfilechooser\qwwfilechooser.cpp(79) : error C3083: '{ctor}': the symbol to the left of a '::' must be a type

To copy to clipboard, switch view to plain text mode 

Both lines look like

int mar = style()->pixelMetric(QStyle::QStyle::PM_DefaultFrameWidth, &opt, this);

int mar = style()->pixelMetric(QStyle::QStyle::PM_DefaultFrameWidth, &opt, this);

To copy to clipboard, switch view to plain text mode 

Removing redundant "QStyle" fixes compilation, but I've now got some linker errors that I'm trying to sort out.

P

[wysota]

Hmm... you're right, I don't know how the doubled QStyle happened to be there. If you define WW_NO_FILECHOOSER in the project file, those problems should vanish - the widget is not ready yet anyway... What exact linker errors do you get?

[pdolbey]

Its the plugin that's giving the problem. The "widgets" project has created dll and lib files sucessfully. Running within Visual Studio, I get

I'm pleased to announce the immediate availability of wwWidgets 0.8

The main effort has been put on compilability with gcc, msvc and mingw and compatibility with Qt4.4. Apart from obtaining those goals (at least I hope so), the set is extended with new widgets such as:

QRichTextEdit - a widget that turns QTextEdit into a usable selfsufficient rich text editor


QwwButtonLineEdit - a lineedit class that combines the line edit with a programmable button.


Derived widgets such as QwwClearLineEdit, QwwResetLineEdit and QwwFileChooser are also available.


Full capabilities and full Designer integration is available for very recent (late January 2007) snapshots of Qt 4.4, but the whole set should compile with earlier snapshots as well as Qt 4.3 and Qt 4.2.

Please note that though wwWidgets are fully usable, the version 1.0 has not been reached yet and so the API and ABI may (and probably will) change in future releases.

The website has not yet been fully updated with docs and descriptions. In any doubt, please ask questions - I will gladly answer them.

Visit http://www.wysota.eu.org/wwwidgets for more details and download. Binary releases of the set may be available upon request.

All comments and other feedback is greatly appreciated.

[pdolbey]

wysota,

As you must realize, I await these release eagerly. However your website doesn't seem to responding at the moment.

Pete

[wysota]

Hmm... really? It works fine for me.

Attached you'll find the 0.8 source code archive in case you continue to be unable to access the website.

[magland]

Everything works great with MinGW. However, when I try to compile/install using msvc, I have some problems.

I did:

qmake
nmake
nmake install

Everything seems fine, but when I compile and run an example, it complains that it is missing mingw dll. ???!

So, I tried to link directly to the library (i.e. not using CONFIG += wwwidgets) and everything worked fine. So it must be a problem with wwwidgets.prf with msvc. ??

I am using Qt 4.3.3

[pdolbey]

Hmm... really? It works fine for me.

Attached you'll find the 0.8 source code archive in case you continue to be unable to access the website.

I'm on a highly restricted environment at work, having to run the internet via Citrix, but I don't normally receive the tcp timeout error I got unless the target site is unavailable. Anyway thanks for putting the release out as an attachment. I'll grab it from my home machine later - and see if your web site is reachable from home. I'll only add to this thread if it isn't.

[wysota]

I'm very happy to announce the immediate availability of wwWidgets 0.9.5

This is one of the last steps towards the 1.0 release. Since 0.9 the API is practically frozen, so no new widgets are introduced. This release deals mostly with documentation and installation issues.

Special thanks goes to Paul Buhr who provided feedback related to installing the set on MacOSX. If the patch is correct (I had no means to test it) the library should install (more or less) cleanly on all three major platforms.

Remaining steps until 1.0:

• implementation of QwwRichTextEdit (icon issues, list issues)
• missing documentation
• examples
• qconfig like defines to strip out functionality easily

When 1.0 is released, new widgets will start making it into the set so keep your fingers crossed.
Upcoming widgets:

• a breadcrumb widget
• a marquee widget
• an image viewer
• a calendar button
• a progress/waiting notifier (the circle shaped thing stumbling through many modern websites)
• IP line edit
• and more...

• wwWidgets homepage
• wwWidgets Reference Manual

Installation instructions:

qmake
make
make install # superuser privs required
make register

Update instructions:

qmake
cd widgets # install the widget set first before compiling the plugin
qmake
make
make install # superuser privs required
cd ..
make
make install # superuser privs required
make register

The last step is only required if you use Qt4.4 or newer. It registers the compressed help documentation with your Qt Assistant.

All feedback is welcome and appreciated!

All feedback is welcome and appreciated!

• If I use the Oxygen Style on linux the height of all lineEdits is not correct (its very narow).
• Is it possibel to ship translations together with the source (like the qt translations)?

great widgets, thx :-)

[wysota]

If I use the Oxygen Style on linux the height of all lineEdits is not correct (its very narow).

I'm aware of that but that's unfortunately a bug in Oxygen that's causing this. The problem is the bevel in line edits in Oxygen is treated as if it was inside the text box's rectangle and not outside.

Is it possibel to ship translations together with the source (like the qt translations)?

If there were such translations, they would probably be shipped. If you provide them, I'll be happy to include them in the next release.

great widgets, thx :-)

You're welcome

[pospiech]

Do you except feature requests?

I require something which could be called doubleExponentialSpinBox. That should be a SpinBox that excepts double values but displays them as "1234.0234 e -123".
The Buttons should then increase either the value or the exponential depending on the position of the cursor.
I require this very often since I am a physicist and deal with high exponential values quite often. However it is not possible to display these in any standard spinbox.

Matthias

[wysota]

Do you except feature requests?

Sure, why not.

I require something which could be called doubleExponentialSpinBox. That should be a SpinBox that excepts double values but displays them as "1234.0234 e -123".

This can be done with the regular double spinbox by reimplementing two methods.

The Buttons should then increase either the value or the exponential depending on the position of the cursor.

Ah.. I see... seems nice, I'll look into it.
