CEGUI (Crazy Eddie's GUI) Forums

I'm trying to find out, how I can check a CEGUI::Spinner, if the field is in focus. I mean, if you clicked on the field, so you can enter numbers, etc...

Is there a way, how I can check, if a Spinner is in focus?
E.g. the EventMouseClicked event is not enough, because I don't want the Event powered one time, if we click on it. I want it to power the whole time, the spinner is in focus...

Thank you in advance

Add the following method to class CEGUI::Spinner (or to a class u inherit from it)



I'll submit this to cegui later on.

Add the following method to class CEGUI::Spinner (or to a class u inherit from it)

What class do you mean?

Yaron is right, you need to get the isActive() status from the spinners editbox. You can query the editbox by calling getEditbox() on the spinner and then call isActive() on it. This function return true as long as it has focus (= the caret is active in the editbox).

IIRC this function can go straight into v0-8 since you just add a function to the API and don't change or remove any API function that existed before.

I don't get it...

Let me say, I have a Spinner called "widthSpinner"

I generate it like this:


And in the Header I set m_widthSpinner.

Right.


Now I want to check, if the Spinner is active, so I think i have to do it this way:


And in the fact, that I want to check this like a bool i put it into a if-statement:


But then I get an error and it says, that I don't have access to the function, declared in line 319 in Spinner.h...
What is wrong with that and how can I fix this?


Thanks in advance

Gykonik:

Indeed, u can't access the method "Spinner::getEditbox" coz it's "protected". Read here. Therefore you'll have to add a method to class CEGUI::Spinner (thus changing cegui's code), or create a class that inherits (say MySpinner) from it and add this method to that class. Then, use the class MySpinner rather than Spinner.

Ahh, now I got it....


Now I added to the Spinner-class in Spinner.h this:


And down, outside of the class, I did this:


Now it says me, that getEditbox isn't definded...
But it is, as a protected class

Gykonik: That's coz the class Editbox is defined in another header file. To use it, you'll have to add:



to the top of the file "Spinner.h". But don't do that! Coz u have a deeper problem. In general, methods should be declared in the header file (i.e. a ".h" file) (inside the class definition, of course), but be defined in a source file (i.e., a ".cpp" file). Otherwise, if the header file is included by several source files, from the compiler's perspective the method would be defined multiple times, which is an error.

So that means u should leave the declaration:



inside the definition of the class Spinner (in the file "Spinner.h"), but move the definition (i.e. the method's body):



to the source file (i.e. "Spinner.cpp"). Then everything should work fine. You don't have to add:



to the file "Spinner.cpp" coz it already includes that file.

But I don't have a Spinner.cpp file... (Maybe it's in the library?)

I only have a Spinner.h file

Yes, it's in the library.. you must make the changes in "Spinner.h" and "Spinner.cpp" in the cegui source, then build cegui again and then install cegui again.

srsly?

Gykonik: my assumption was that as u use cegui, you've already managed to build it, haven't u? And if so, what's the problem building it again?

Cheer up, buddy, I'm already all in tears from all your sad faces.

It takes time...

On my linux machine rebuilding cegui takes less than a minute. If your'e on Windows, s***w u

I'm on windows....

You can rebuild it for me, if you want to xDD
