promotion problems with designer

[szisziszilvi]

Hi,

I have a small class derived from QPushButton for the cases whenever I need a file loader button, and I use my class with the promotion technique. I work on XP, and I use the Qt Creator. Whenever I change something in the after I try to build the project I get the error message:
buttonfledialog.h: No such file or directory.

This appears in the generated ui header at the line where it tries to include my buttonfiledialog.h like this:
#include <buttonfiledialog.h>
which of course causes the error message.

The problem can be solved with changing this line to
#include "mypath/buttonfiledialog.h"
but in this case I will have the very same problem whenever I change something in the user interface because the ui header will be every time regenerated with the wrong include line.

Now I would like to ask if there is a way to avoid this mess, so how can I "teach" the creator (or the system itself, like adding a line into the pro file) to use the proper path?

HI,

as you can see in image

6278

you can specify namespace for class name and path for include.
If you check "Global Include" uic generates


#include <ns/mybutton.h>


instead of



#include "ns/mybutton.h"


this is the output in "ui_Widget.h"



#include "ns/mybutton.h"

...

class Ui_Widget
{
public:
...
Ns::MyButton *openFileButton;
...

if I do this:
Promoted class name: NS::buttonFileDialog
the automatic header file name will be ns_buttonfiledialog.h in the third line. Which generates in the ui_mainwindow.h this line:
#include "ns_buttonfiledialog.h"
which is of course wrong.

I tried to use my own path, so in the three input areas have:
Base class name: QPushButton
Promoted class name: NS::buttonFileDialog
Header file: D:/mypath/buttonfiledialog.h
(and global include unchecked)
which leads to errors because the namespace has not been created. I have error messages with this line in the generated ui header and furthermore wit each line in the other files where I use the button which was promoted to buttonFileDialog.

But based on your advice I found the solution. The hard point was that I had the global include ticked, which is incorrect if I have the header in a custom folder on the computer. But I have never declared a custom namespace, so forcing this will obviously cause errors as well. The final answer is then not to use either the namespace or the global include.

Base class name: QPushButton
Promoted class name: buttonFileDialog
Header file: D:/mypath/buttonfiledialog.h
(and global include unchecked)

Remember tha you can change the automatic proposed values in Promote Widget Dialog

If you want to use "D:/mypath" as Include path I suggest you to do this

Promoted class name: NS::buttonFileDialog
Header file: buttonfiledialog.h
(global include unchecked)

AND

add in your .pro file this line



INCLUDEPATH += D:/mypath
