* refactor TaskPostDataAtPoint::on_Field_activated()
* show results in a label instead of message box to reduce clicks
* in output window also print field and position as the pure values are useless
- on changing a point coordinate, either by clicking a point or by changing the spinbox in the dialog, the color bar must be refreshed and data must be evaluated for all fields along the new line
- recoloring the gradient bar for a single point is senseless. One therefore already got dozens of errors that max = min in the console. Therefore don't recolor for point filters
fixes#7008:
- the point data must be read also when the center changed
- when the dialog is called it has only the value for the current field, thus recompute the feature to fill all fields with data
- on clicking on a mesh point display the value at the clicked position
- due to the object's recomputation at the start, a complete recomputation (for the whole pipeline) is needed on closing the dialog
- we cannot assume to have a geometry at position (0, 0, 1) this initialize at (0, 0, 0)
- also don't hardcode the unit in the UI file
- also fix wrong property description
- property "Radius" is not used in the code and it seems it is only there as copy paste bug once the point filter was implemented. However close to a release, keep the property and just mention it is unused.
- in contrary to other filters the properties have no unit handling
(there are several bugs in line filter and to fix them, unit handling is necessary)
- occurred when changing Field to "None"
- also remove doubled and unused code and add a blank line to separate the different filters in the code better
- the App part used already units but the dialog worked unitless. This is error-prone and confusing. Therefore use unit widgets in the dialog.
- also fix issue that unit was not reset (after e.g. a temperature maybe a unitless strain should be shown)
- at the moment you cannot get the result data, for example to make your own plot. Also for the line you might want to have unequal x-steps etc. Especially for the data point filter not getting the data actually makes the tool quite useless.
- therefore set the properties to output
- they all had the name "figure 1"
- thus make the name unique and this way also enable to have several plots open displaying different result types (for the line filter)
* [FEM] fix linear filter plot
the plot one can create from within the linear filter is at the moment detached from FreeCAD's main window.
This PR fixes it the same way as in https://github.com/FreeCAD/FreeCAD/commit/920e8e046
