Modifying an existing dialog?

[hokieengr]

I'm sure this has been covered elsewhere but I can't seem to find anything recent so I'll ask.

Is there a preferred method or modifying an existing dialog? Are we expected to use Qt Designer or can I just hand edit the text files for simple things? If we are only to use Designer, should we be using Qt 4 or 5?

Thank you!

I use Designer for Qt4. The Qt5 migration isn't quite ready as far as I know.

I asked this in a different thread because that's where the conversation meandered to but it's probably more appropriate to ask it here.

I've added a Pref checkbox to an existing dialog using Qt 4 Designer after I built and installed the widget library. After rebuilding my option is there and clickable, no issues.

However, I thought by using a PrefCheckbox widget that saving and restoring the state of the preference would be handled automatically but that does not seem to be the case. So that's my question: what's the proper procedure for saving, restoring, and accessing the current state of a preference?

As far as updating, the magic is in the red box.

Access in C++

Code: Select all

    Base::Reference<ParameterGrp> hGrp = App::GetApplication().GetUserParameter()
        .GetGroup("BaseApp")->GetGroup("Preferences")->GetGroup("Mod/TechDraw/General");
    m_sectionEdges = hGrp->GetBool("ShowSectionEdges", 0l);
    m_handleFaces = hGrp->GetBool("HandleFaces", 1l);

Sorry, don't have a Python example handy.

That's kind of what I figured and what I believe I did. I'll confirm when I get home. On your machine, if you add a new Gui::PrefCheckBox, fill out the magic red box, save, go into your build directory and fire off make (and make install I suppose depending on how you do it), does the resulting checkbox work? If you click it, click OK, and reopen the dialog--does the state automatically get saved? Is there another step or script I have to run to let the magic know about my new little box?

Thanks a ton for the C++ example. That will help a lot. No need for Python right now since I'm working in C++.

A couple of things I can think of off hand:

Code: Select all

void DlgPrefsTechDrawImp::saveSettings()
{
    cb_HidLine->onSave();
    cb_Angle->onSave();
    cb_Faces->onSave();          //<<<<<<<
    cb_SectionEdges->onSave();
    cb_PageUpdate->onSave();

    pcb_Normal->onSave();
    ...
    ...
    void DlgPrefsTechDrawImp::loadSettings()
{
    cb_HidLine->onRestore();
    cb_Angle->onRestore();
    cb_Faces->onRestore();     //<<<<<<<
    cb_SectionEdges->onRestore();
    cb_PageUpdate->onRestore();

    pcb_Normal->onRestore();

and IIRC you need to press Apply first and then OK (??I always do it this way. Don't know that it is strictly necessary).

Of course I swear I did all that before posting but it worked this time....
