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
