Changing UI elements

[mshavliuk]

Description

In the app there are some buttons that do nothing useful for a current state of the project or inevitable lead to an error after clicking them. Disabling and hiding them will improve the app usability and declutter the interface a little bit. Below is the list of such buttons I found:

Mesh Visualization tool

• Visualize volume

  Problem: This button is always active, even though the project might not have a FEM mesh, thus no volume to display. Clicking this button in such case will lead to an error:

  Error

    Index in position 2 exceeds array bounds.
    Error in zef_plot_volume (line 319)
    tetra_c = (1/4)*(nodes(tetra(:,1),:) + nodes(tetra(:,2),:) + nodes(tetra(:,3),:) + nodes(tetra(:,4),:));
    
    Error in zef_visualize_volume (line 4)
    zef_plot_volume;
     
    Error using matlab.ui.control.internal.controller.ComponentController/executeUserCallback (line 427)
    Error while evaluating Button PrivateButtonPushedFcn.
  

  Solution: Disable this button whenever the FEM mesh does not exist. Also, It would be awesome to add an explanation for disabled button in a tooltip.

  Solution example

    zef.h_pushbutton31.Enable = 'off'
    zef.h_pushbutton31.TooltipString = 'You should create FEM Mesh first'
  

• Frame / Movie

  Problem: presumably, this button only makes sense in case if the model has more than one frame.
  Solution: Disable this button when there is no more than 1 frame in current model

• Cutting plane mode

  Problems:

  1. It looks like it relates to clipping planes, but it uses another term "cutting plane" which is a little bit confusing
  2. It stays active even though the clipping planes are deactivated

  Solution: Disable when all clipping planes are deactivated. Rename to "clipping plane mode"

• Plot graph button

  Problem: This button seems to work only after the FEM mesh is generated. Otherwise it causes the following error

  Error

    Error using matlab.ui.control.UIAxes/set
    Value must be a 1x2 vector of numeric type in which the second element is greater than the first element or is Inf.
    
    Error in zef_histogram (line 15)
    set(gca,'ylim',[min(hist_y) max(hist_y)]);
    
    Error in zef_plot_graph (line 9)
    eval([g_list{2}{g_ind} '(' v_name ');']);
     
    Error using matlab.ui.control.internal.controller.ComponentController/executeUserCallback (line 427)
    Error while evaluating Button PrivateButtonPushedFcn.
  

  Solution: Disable this button whenever the FEM mesh does not exist. Also, It would be awesome to add an explanation for disabled button in a tooltip.

Figure tool

• Reset/Play/Stop/Pause buttons and "Loop on count" checkbox
  Problem: these controls do nothing for a single frame project

• Many sliders are not having any effect in certain context. They might be hidden or disabled

  • Time is only used when there is more than 1 frame
  • Transp. rec, Transp. surf, Transp. sens, Transp. cones, Transp. add are always shown and active even though the Figure Tool might not even show surfaces, cones or sensors at a given moment. This often leads to confusion when the wrong slider is used mistakenly.

Mesh tool

• Meshing accuracy control
  In practice this value should always be 1. Changing this parameter leads to degrading accuracy.
  Solution: Remove this input field
• Downsample surfaces
  Solution: Rename this checkbox to Resample surfaces
