QML and Qt Quick

@ltlnx
Me again, who knows nothing about QML :) Wouldn't have thought that theme would go as far as suppressing display of combo dropdown items completely. Are you able to quickly try your thing in something other than your "KDE desktop", like GNOME or whatever?

@Bob64

Thanks for your reply.

Not only does the closing strategy require the mouse to click outside to disappear, but also a button to control closing and showing. Clicking on the button triggers the closing strategy at the same time, which will cause the window to close and then open again.

Yes great, thank you.
I add another thing which is to take into consideration the number of lines once the component is completed, because if I manage the margin directly during initialization, it does not work:

anchors.leftMargin: contentWidth > width ? 12 : 4
anchors.rightMargin: contentWidth > width ? 12 : 4

... Component.onCompleted: { anchors.leftMargin = (lineCount > 1 ? 12 : 4) anchors.rightMargin = (lineCount > 1 ? 12 : 4) }

Make the topic as "Solved" as well.

And as a bonus question, I fail to understand why modules are sometimes built as plain modules and sometime as libraries, by adding this (and then linking as a plugin):

qt_add_library( StyleModule STATIC )

In that case, also, is this needed in the main.cpp:

Q_IMPORT_QML_PLUGIN( StyleModulePlugin );

It works with and without, so I'm missing the point.
There are a lot of examples circulating online, for various versions of Qt and all of this has changed quite a lot. The documentation being pretty thick, it's not easy to find up-to-date basic guidelines.

Explanation or examples of use cases welcome! Thanks!

bro ur the goat ive been stuck on this for hours, i think the key was wrappping the whole delegate in a component on the qml side

@GrecKo said in ListView not displaying results of a QSortFilterProxyModel.:

In your debug output, it displays "NOT found" then "found", does that mean that the proxy model eventually returns true and your line is displayed in the ListView or does the ListView still doesn't display the delegate even thought the proxy model returns true?

It's the latter. The "NOT found" occurs at application startup (I'm not sure why; I guess the QML engine pre-loads some stuff), but the "found" occurs when I navigate to the screen containing the ListView.

Also your code is incorrect, I don't think it should matter here but better safe than sorry. You are using a QModelIndex from your proxy model when calling your source model data method, you are not meant to do that.
Instead use a QModelIndex from the source model:

QModelIndex qmi = m_equipmentModel->index(sourceRow, 0);

OK, fixed that. Thanks.

Also are you invalidating your filter at the right time? (when spaceContainsEquipment result is suspected to change)

This may be the problem. I'm not explicitly invalidating the filter, because I'm not sure where to do it. The space model contains a list of spaces, each of which in turn contain a list of equipment. Do I need to send a signal from my space model to my equipment proxy model when that list of equipment changes?

Thanks...

EDIT:

I just noticed that upon closing and reopening the screen with the ListView, I get another confirmation from the proxy model that the equipment is in the space list, and...the delegate now shows up! I don't know what to make of this, but it's certainly interesting.

@Asperamanca Sorry for late response, and thanks for your answer, it's helpful, I will try that!

@MaximBozek
Bear in mind that I don't know anything about QML, only non-QML/widgets Qt. There I would expect to be able to go qDebug() << QFile::exists(":/fonts/Onest-....ttf") (I think that is right for non-QML, you could try on "qrc:/fonts/Onest-....ttf" but I believe the qrc is for QML only) and see it confirm that it can find that resource file at least. Can you do something similar from QML? I don't know that you can use any C++ code so I have to leave it to you).

I don't know anything about whether fonts actually have to be installed or not. One would have thought not, they would work from the resource file, but I don't know.

Hi,

Did you follow the suggestions @Pl45m4 made on this thread ?

@Vermithor said in Embedding external application on QML screen in Linux:

These things are helping to bring a new window but unable to run the VS code within the window

I don't see the reason why you want to do this... but apparently you haven't read the whole thing.
How to embed foreign windows is indeeed described there.

@chids
This doesn't work for me。

I have restarted qmls.exe and cleared CmakeCache。

Yeah, report a bug, please.
