| Summary | 0000111: Make the task panel accessible from python | ||||
| Description | The task panel is really cool... One single non-obtrusive place where all the UI workflow is concentrated. I think it would be nice to have it accessible from python, so anything where you need user input can happen there. If someone can explain me a bit how it works on the C++ side, I can try... I suppose the best way would be to make it something that works like the Console? I also think we could add a bit of styling to it (using the same gradient as the 3D view, maybe some special icons, something like that...) But that's purely cosmetic and can be thought about later. What do you guys think? | ||||

Thats more complicated ;) The TaskPanel has multible usage. And is somwhat still in expermimental use. I used it a lot in Robot. First usage is the Dialog. Werner used it e.g. for the Placment dialog. Its blocking and diactivates all commands (which change the document) until the user accept or discards.. The other usage is the real TaskView like in Windows Explorer in XP. Which show stuff dependend to the selection. A simple usage is the: Gui::TaskView::TaskWatcherCommands which you give a selction filter and and a Gui::Command list he have to show in case the selection filter match. Exampel you find here: src/Mod/Robot/Gui/Workbench.cpp Line 54. You besides commands show any kind of dialog (ui) dependend of a selection filter. The base class is the so called Gui::TaskWatcher and normaly this "handler" get registered when the workbench is opened. So every workbench kann have its own set of TaskWatcher to present different behaviour.... I have to think about an interface in the workbench to expose this stuff. Since I still quite experimenting with this stuff, not quit easy... |

Actually I just wanted to use it as a placeholder... My idea was to get rid of the draft command bar (or at least offer the choice) and use the task view instead. It would be pretty convenient, you click the line button, and the line options appear, same as Werner did with the Part tools. This would save a good amount of screen space and concentrate all user input at the same place. Basically I'd like to be able to do this with python/pyqt: TaskExtrusion::TaskExtrusion() { widget = new DlgExtrusion(); taskbox = new Gui::TaskView::TaskBox( Gui::BitmapFactory().pixmap("Part_Extrude"), widget->windowTitle(), true, 0); taskbox->groupLayout()->addWidget(widget); Content.push_back(taskbox); } If I understand well, the Ok/Cancel buttons are part of the TaskView itself and not of the inserted widget? Can you explain me a bit more how the TaskView works or where I should look? I've already done python bindings, maybe I can have a try some day... |

Mhh, the buttons are showed by the TaskView if you open a TaskDialog. The TaskDialog can decide what collection of buttons it whant to show: http://doc.trolltech.com/4.2/qdialogbuttonbox.html#StandardButton-enum The TaskBox is a smaller component (one you can switch open and close). A TaskDialog can consinst of one or more TaskBoxs. While the TaskDialog is aktive all GuiCommands to change the document are greyed. That ment as long the Dialog is open it hat the sole ability to alter the document. But that can also be changed. On the other hand are the TaskWatcher which are added to the TaskView by e.g. the Workbench. They are basically allways present but invisibel. The TaskView allways checks the state of the selection and what is in edit and view the TaskWatcher for that e.g. object selected (or edit). But you could also show some TaskBoxes which are permanent on in your workbench. But Im not quit shure if your TaskView get to much crowded that way.... ;) |

Hmm that looks amazingly perfect! To follow with the draft workbench example, there is indeed a part that changes form command to command (and that must impeach other commands to run) and a part that is always there (the right part where you can choose line color). So basically when you want to show something on the TaskView you insert a TaskDialog in it, then you stuff it with the taskboxes you want, then when you are done you remove the taskdialog... Is that more or less right? Is there an example of how the taskwatcher is used somewhere? |

The robot workbench use it quit a lot in both forms, as TaskWatcher and TaskDialog. I will use it also extensifly in the Sketcher/PartDesign workflow I work at the moment... But never the less - I see the User interaction still as a field of discussion. Im not quit shure what I think of is the perfect way.... |
|
|
Yes, me neither. I'll have a look at how the robot workbench uses it... |

In the meantime I made a very small modif at the task panel in rev 3316 (made it use the current palette instead of qt default) and i modified a bit the colors to make it more stylish... |

I had a deeper look yesterday, and I begin to think like you, this is far from easy... One could make something similar to the mechanism to add an .ui page to the preferences dialog, but the usability of this would be pretty limited... (no easy way to make the .ui page update things in realtime on the 3D view, or vice-versa) And inserting directly a pyqt widget into the taskview system looks very complicated. Maybe let's close this subject for now? Or we keep it for some later release than 0.11? |

> One could make something similar to the mechanism to add an .ui page to the preferences dialog, but the usability of this would be pretty limited... No absolutely not. Using Qt's introspection mechanism this is as powerful as the generated python sources. Using the findChild() method of a QObject you can find all children you need. I have almost finished now the python binding and also provide a reference implementation how to use it. Have a look to Taskpanel.py in the TemplatePyMod folder. |
