First Experience With Activities
Using 4.7 from Debian Experimental (emphasise that word). There are a zillion activities available shown on a strip which is quite large. I named my normal desktop main, gave the second activity a name. So far, so good :-). I started placing widgets/icons on the second actiivity. Going back to the first ... it was totally blank, just the panel. Had to put everything back. Still, the cashew is gone (not the worst loss). I suppose this occurred because once another activity is populated, the config file format changes and boom! Second activity has its cashew. Got that applications to run dialog, mostly covered by the activity strip. Need a different UI for this one--also, when I later on, do want apps, how to I get that back and use it? What I would like to see: Nice ways to move, copy, SHARE, widgets among activities. Right now, they can be shared on the panel but that has limited realestate. Right now, each activity starts with just the panel, must do everything from scratch. Instead of the strip, what about an add-activity dialog with templates which would offer the pre-populated activities presently offered farther along the strip. Then, more of a UI for the activity's mode, properties, applications, etc., on a clean UI field. Another wish-list: The folder-shelf view could be quite useful but could use transparency and multi-column/icon view option (extender would need another treatment). Right now to see anything here, it takes up too much space. The folder view (postings have complained about it) was working fine until the new activity was populated. Now it does not keep its position. All in all, this is shaping up quite nicely. Since our widgets can do everything metro can (sue 'em!), one can really do most anything in KDE/Plasma! ___ Plasma-devel mailing list Plasma-devel@kde.org https://mail.kde.org/mailman/listinfo/plasma-devel

In this case, the right-most (last) action icon overlays the runoptions icon. Since they are not exactly the same positions, one can actually get to both with a little skill. However, this is not the desired placement, obviously. Workaround tried was a dummy action with no visible icon.

There are two ways of getting actions into a runner: As a dropdown from the configure icon on the right or as action-icons over the subtext area. Ne'er the twain do meet. As a drop down, the app remains visible, one has text available (tooltips do not work!) but one does not have access to match data. As activities, one has the data. There are not textual clues and tooltips do not work. As soon as one of the activity choices is done, the app closes. Is there any way to keep the app open (or even rerun the matches)? An activity might want to inspect properties of a file which I might want to open afterwards. This is certainly not a kludgy hack to want to accomplish.

Here is the problem: I often stumble over the same usability problem. Normally I have my plasmoids locked, because I don't like it when this edit- bar (don't know the name) appears when the mouse is hovering over a plasmoid. But then I want to add a new plasmoid. To do that I've first to unlock the desktop, add the new plasmoid, move it to the correct location, and lock the desktop again. That could be easier. Here is my proposal: It would be nice if adding plasmoids would be possible even if the desktop is locked. After dropping a new plasmoid it should be in a kind of floating state (like when pasting in GIMP). This state allows to move this single plasmoid around on the locked desktop. When finishing moving, e.g. by clicking somewhere else on the desktop, the plasmoid should loose this floating state and is locked on the desktop at the current position like all other plasmoids. The floating state could be highlighted with some glowing border or shadow to show that it is floating. What do you thinnk about this idea? Is it possible to implement something like that? regards, Gerhard I would not mind this at all! Locking to avoid inadvertent changes is good.

Re: activities overview, take N
I have been reading or glancing this thread for a while (many longer posts are unreadable because of all the variations of included text being answered). If we are not talking about a one-to-one desktop-activity relationship which might be the most straightforward to understand, in other words an activity is a group of icons, windows, tasks and not a desktop per se The current zoom out, set up, zoom in, find them all different on next login...is hopelessly slow, incomplete and broken. I woud scrap it. Activities might be connected the current desktop from a right-click, from the panel, dashboard and/or from an appropriate previewing plasmoid. These activities could be containments based on the current folder view but could contain (additionally) plasmoids (?) and functioning .desktop files. If we want tasks running when the activity is brought up, we would probably want them started up where they left off the last session. More difficult if impossible for many apps. An activity and its data might be referenced or contained in one folder. A trivial example is the desktop folder containment itself or an appropriately filtered folder-view of the desktop folder. There could, of course, be more than one or none on any desktop, the same activity might be on several desktops. There would be no implicit relationship between activities and configured desktops. While a Rubic's cube of activities/desktops might be cool, I doubt it would really be useful.

Applet::init()

Is this the one that has been on kde-look for a while? Sounds like it. This is a worthy revamp of the original device-notifier plasmoid and in 4.3 it is actually readable. The last mounted tooltip is of questionable usefulness. This baby, at least the last kde-look.org version of it, is exercising dbus and hald and plasma-desktop to significant percentage of CPU activity. This indicates a big code problem because this adds to the overall daemon CPU glut that can slow plasma and kde4 to a fast crawl. The kde4-supllied applet does NOT have this problem. I can look myself but am no expert (OK, time for more documentation as plasma's own API and all these activities and delegates and such are making my head swim--ok with anticipation!).

Re: containing plasmoid crashes
A similar problem has seemingly been solved, by Google. Since google's browser is opensource, one might take a look. Every one of those tabs, plugin processes, etc., is a separate process, shows up on top as such. I have an upload going on now, apparently in a chrome process initiated from a website. No browser is showing at all--closed it. Their approach is still very beta, has some interesting problems, but it works. We would probably want to use dbus (I do not know whether they do). Example of their success: Clicking a link in kmail, for example, will spawn that as a tab in an existing chrome browser if one is running. Caveat--if one died and is still an existing process, one must kill it before chrome will work correctly. Beta. Wow!

Re: 4.4 call for runners (ideas)
For us diehards that are resisting software over which we have little or no control, i.e. nepomuk: A runner to interface with recoll (I run its indexer at nice 19 and I do not know it is even running) -- this can simply issue command lines to recoll and parse their output quite simply (give me a skeleton and I can play with this myself!). I am sure we can think of others. Other ideas already proposed: Kmix -- why would I want to control that from krunner. I think that the panel applet does the trick more than adequately. Would I really want to put up krunner and type in mute or volume=75? Anything else that is manageable with a click or two which would require more than trivial text-entry to krunner, to me, does not belong there. A dialer for skype or any other phone app--i.e. command line to kall or a message to my phoneapplet? May have its place in krunner but an applet itself seems more straightforward.

Latest from playground SVN. After hand entering stuff like akonadi/monitor.h since I do not have the Akonadi/Monitor files available, it build OK. My applet's sequence no longer gets to 1st base.

When I request it, I see in the console contact data items rather than sources and then the explorer crashes. I most likely do not want ALL the hash items all at once like that. What I had been getting in dataUpdated was the source (Contact-) and the data-hash. Will I still get this (and the console output has changed) or is this all changed as well.

Re: Fun with Akonadi Dataengine
Latest from playground SVN. I re-downloaded and compared with the older code.

Such could alleviate some of the panel delay I encountered when doing this directly in init(). However, this is a small amount of data at this point. The delay was more from the log-jam on kde/plasma startup. For example, with the older dataengine, it took almost 90 seconds before I got the contacts to start dataUpdate-ing. Later on, run from the plasmoidviewer, this same thing completes in several seconds. With the new code, I will not have any useful return from query until I have the equivalent in dataUpdate.

The applet in the panel apparently did not crash (the desktop and panel came up) even though the plasma command certainly showed all that stuff. In any event, I am going back to the older code until the problem is resolved since I cannot test the applet or dataengine with the new code. ___ Plasma-devel mailing list Plasma-devel@kde.org https://mail.kde.org/mailman/listinfo/plasma-devel

You should be able to just connect to dataUpdated() for that collection and If it's necessary to use a timer, there's something wrong with the interface. It should be completely event-based, no? The problem I found is (maybe because ContactCollection-# loads other sources rather than its own data-hash) is that until all the individual contact sources have been loaded into the engine (shown on console messages if I am running in the plasmoidviewer), connectAllSources does nothing. It needs be repeated when sources are in fact available. I am not saying it SHOULD be this way but that it how I find it to be. 2. At 1st timeout, I do the a query(ContactCollections) then if I find a suitable key, connectSource, i.e to ContentCollection-6. You can just do that in or from init(). Why use a timer here? The panel on which the applet is nested delays coming up when I do it directly in init(). 3. After that, I connectAllSources at 1 second intervals until dataUpdated gets called. At this point, I stop the QTimer and am now receiving the contacts. Using these, I assemble my phone book into a QListWIdget. You should query ContactCollections and then in dataUpdated(), you check if the source is I query to get the ContactCollection-# key and then connect to that which initiates the load of all the Contac-# sources after a delay. Why in one-second intervals? Is it blocking for you otherwise? I could have used another interval. The point is that I am NOT blocking so everything plays naturally. If you're unsure how to do it, you can look at lionmail.cpp. There, it should be async and pretty similar to what you want. URL? Well, what exactly is it that you actually want? :D To build a phone number directory from the contacts. One contact may give me several entries. All easy by checking the keys.

It is also why it's all the more important to have display of data fully async, and not depending on complete initialization of all data on startup.

The loading of data in the dataengine is async. Don't block on it but react to signals announcing new datasources instead. Look at lionmail.cpp for an example.

Re: playground/base/plasma/dataengines/akonadi
Great.
I downloaded and compiled.
I still get no data sources in the explorer and in some test code which
would simply show the sources() list.
SVN commit 923483 by sebas:
birthday, location and photo for the akonadi dataengine contacts part
In more general, the dataengine works as follows:
For email:
---
- request EmailCollections, you'll get a list of EmailCollections-id
as key and the name of the collection as value.
(The list of collections is loaded on demand)
- Choose one of those collections by request the ID
(EmailCollection-id). The dataengine now queries Akonadi for all
emails in that collections and will add a new source for every email. In
you dataUpdated() method, you can simply check if the
source.startsWith(EmailCollection-) and then query the data from that
email.
Properties you might be interested in for those email source are:
- QDate DateTime
- QString Subject
- QString From
- QString To
- qlonglong Id
The Id can be used to query Akonadi for the body of the email. That part
is not yet included in the Akonadi engine, but might come in the future.
For Contacts:
--
- request ContactCollections, choose one of those and request
ContactCollection-id.
- request one of those collections (ContactCollection-id)
- New sources for every contact in that collection will appear. You can
now get at the Contacts data through the following fields in that
particular source:
- double longitude
- double latitude
- QString Organization, Role, FullEmail, Name, Department, Emails,
various Phone- numbers
Work to get those datasets more complete is under way. What's in should
already provide for most of the use cases you can dream of.

Dataengine Questions, Proposal?
I would like to try the dataengine that interfaces to KDEPIM contacts. So how do I: Register the applet with it/for it? What datasource do I get? Obviously this is not a polled item and getDataSource should trigger the signal. What is in the hash--do I get the datasource for one contact and have this contact's data items in the hash or do I get datasource contacts and have all of them to search or can I do it both ways? == Is there or will/can there be a dataengine sitting on X-events such as keystrokes and mouse-events. This would obviously trigger quite often if one is using these devices. Keyboard and mouse event classes are altready defined in qt and would also carry the window handle that owns the event. For what would I use such an animal? LIve spell-checkers a la Kisa, instant translation, instant search to recoll/beagle, google, answers.com, etc.In an opensource rather than proprietary maner. There is a color-picker plasmoid and gimp and other apps take choose screen areas using the mouse. What I want to do is retrieve the word under/around the cursor with a key-shortcut and feed that to a search engine, translation engine etc. Plasmoid would bring up a windows with the results. A less convenient alternative UI is to drag text to the applet's icon which is trivial to implement.

Yes. The windows applet from answers.com uses a proprietary, patented method NOT relying on OCR. Babylon's applet uses OCR. (My familiarity with this stuff is a number of years old.) I could say if the owning window has text, get that. If not, go through OCR on some region. In the end, probably simplest to select as you said and either pull off the clipboard or drag and drop to the applet. These both contain mime-type info which can be used in interpreting the selection. The instant information on click is quite nifty, however.

Re: Plasma Applet Direction
More observations: Drawing by svg::paint yields too large a view on the panel (where one cannot adjust the plasmoid size). When I used that, I shrunk the rectangle to 80%. When I used kicon.::paint for the same svgz, I did not need to adjust the rect. Some plasmoids available in repositories or installable from the add widget dialog: I tried one of the system monitor bar-graphs. The old panel applet looked nicer but this is a matter of taste. He had a little space between the bars. Putting this on the panel makes it uncomfortably large. 80% would improve it but again, a matter of taste. There is a dual-plot network traffic plasmoid. Knemo can also put up a plot-- if I want it. Otherwise, it has a simple iconic representation of traffic. The plasmoid might be a decent size on the panel but would take up too much room so I put it on the desktop and shrunk it down. The reduced pixeling interfers with the plots. This one might be better as a single dual line plot like knemo's so one would keep it a bit larger. (Additonally, one can click on and off a textual statistics box but it is not in sync with the plots which lag quite a bit behind. Knemo does this in a tool tip but that view is not live.) The other one I tried is the quick-access plasmoid. This one is using the icon widget so sits nicely on the panel and responds to a proper click, not a press. This one is useful because it is quicker than bringing up a full dolphin. It could use some drag-and-drop capabilities. ___ Plasma-devel mailing list Plasma-devel@kde.org https://mail.kde.org/mailman/listinfo/plasma-devel

How do I do this? it's part of Plasma::IconWidget. you can also do it yourself for custom items by reacting on hover events and starting an animation that uses one of the KPixmapEffects. take a look at the code in IconWidget to see how it does it if you're interested. generally, though, just use the Plasma widget classes. you'll save yourself a lot of grief. there are rather few reasons to do all your painting. Functionality in QIcon as well (iconWidget might get it from there). Since I am using KIcon, well, very easy! Both myself and the original correspondent might have been best off starting with the iconWidget and that has a bona-fide clicked() signal! Without better docs, we start out with the sample code which is a bare applet subclass and no hints of other or added possibilities. ___ Plasma-devel mailing list Plasma-devel@kde.org https://mail.kde.org/mailman/listinfo/plasma-devel

I tried what you proposed... but the above doesn't work with drag/move
operations... :-(
If I click and hold on the applet , instead of moving my popup menu

I cannot vouch for when and if the signalsBocked will return true.
Mouse pressed is not really a click -- this would be press release. However,
this is all we have.

I want my plasma to react on left click on it.
What signal/object should I connect to my slot?
I tried MyApplet::clicked() , but there is no such signal...
I used a mouse click event, wrote my own implementation for that function.
This is not the qt way but no suitable signals are provided. This is what I
did (I am not saying this is a preferred way, simply had no other):
void MyApplet::mousePressEvent ( QGraphicsSceneMouseEvent *ev ) {
if ( signalsBlocked() ) {
Plasma::Applet::mousePressEvent( ev );
return;
}
if ( ev-button() == Qt::LeftButton )
proc_click();
else
Plasma::Applet::mousePressEvent( ev );
}
The first if (I believe) prevents the UI from exercising while the applet is
being moved about.
Right-clicks are handled by the applet's methods, i.e. to place the
context/config menu. There are also hover functions available. No signals.

Plasma Applet Direction
A few observations, queries: 1. Folks seem to be posting applets on kde-look. This is for eye-candy, decorations, screen savers. Applets that treat useful information belong on kde-apps, I would think. 2. What to show? Seems to be a trend of plaster large screen areas with the whole kit-and-caboodle. Very quickly, there is no more room. Why do I need three days (count 'em) of weather forecast covering a percentage of my screen real estate? Same with network stats and system info. 3. KDE3 panel applets/services I STILL use because they have not been ported: knemo, ksensors. There was also a system-monitor (four of them posted on kde- look are not as nice), kweather, kisa (cool live spell-checker), and others which will not work or not function correctly in KDE4. Would love to see (or participate in) their port to KDE4 (not just getting off dcop but going over to provided data-engines). What is distinctive about these is that they present (even a small!!) icon on the panel which shows a useful bit of information (which sometimes I can choose). If I want more, I hover over the icon or click it and then I have access to everything. Examples of current KDE4 applets that work this way are kget, kmix.

Re: kde community plasma integration
[test deleted, very long posting] This is all very exciting, maybe even useful in all or in parts. Main problem is screen real estate. The same reason I do not really like all those lovely superkaramba thingies nor do I use the folder-view plasmoid. Maybe is this could be on ONE of the several desktops in the pager. I want to look at it, I go there, otherwise, I do not look at it. Maybe one parent plasmoid on the panel can alert on updates to any of the feeds. ___ Plasma-devel mailing list Plasma-devel@kde.org https://mail.kde.org/mailman/listinfo/plasma-devel

Applet KConfigGroup vs QSettings?
I want to save/read configuration settings for the user (rather than global settings). The applet class provides two KConfigGroup functions: config() and config( group) Where do these store their data? Global? User? The group name is best the applet name()? user's name? Alternatively, there is the qt QSettings which places stuff in $HOME/.config/organization/app.config or something like that for which I might use organization name plasmoid or plasma and my applet name. Which is best to use for my plasmoid? (Both have isomorphic calls and the KConfigGroup probably calls QSettings or its parent.) BTW, my phoneapplet is on kde-apps.org is anyone wants to play with it. ___ Plasma-devel mailing list Plasma-devel@kde.org https://mail.kde.org/mailman/listinfo/plasma-devel
Closing threads, child QDialog
There are two problems when closing my applet . 1. The ioctl TIOCWAIT thread will not terminate. This may cause plasma not to close correctly (stuck in gray screen until control/alt/backspace). When closing in the viewer, get message: QThread: Destroyed while thread is still running 2. If the applet's dialog box is displayed on close from the viewer (may or may not be a problem when plasma itself closes), the applet will not terminate and the dialog remains visible till a MANUALLY close it. Setting deleteOnClose, calling close, etc., has no effect. These operations are being attempted in the destructor. I could try connecting the QObject:::destroy( this) signal but this might also be too late.

what are the crashes? you need to give us backtraces and example code

The code is a simple pushButtonX-setIcon( KIcon( nice-oxygen-icon);
No useable backtraces. The example I posted was not from this crash.
and of course, one better make sure that the set_ui (generated by the qt
designer) is called BEFORE trying to use any of those widgets, huh :-)
hehe. yes, that's usually a good idea ;)
So I can use icons by name rather than by file-path/resource-path.
How might I do the same thing with the applet::svg images?
you can install the svg using something like this in your CMakeLists.txt
file:
install( FILES list of svgs DESTINATION
${DATA_INSTALL_DIR}/desktoptheme/default/pluginname )
and then you refer to them as pluginname/svgname, leaving off the
.svg or .svgz extension.
OK, but that is just another way of getting a specific path to specific files.
KIcon( icon-name) will pull out the icon for the current KDE icon theme,
i.e. oxygen. Changing that theme will show icons from the new theme.
Is there any way of linking these desktopthemes to KDE's.

However, I have ran into the issue of despite 4 Plasma::RadioButtons having the same parent, the radio button itself is never auto exclusive, so when the user changes their mind, the answer does not automatically switch to the newly chosen choice, and both become chosen so the user could potentially cheat and choose all of the choices.
