I have a uitable and originally last two columns work as popup menus which allows only one selection.
uitable('blah blah blah',...
'ColumnFormat'{'logical','char',cell_array1,cell_array2},...
'ColumnEditable',[true false true true],...
'Data',[blah blah cell_array2 cell_array2])
Now my customer wants to be able to make multiple selections (by holding down CTRL or whatever).
My understanding is that popup menu does not allow multiselect, but listbox does.
I couldn't find a way to put listboxes in a uitable.
I'm open to any other means.
There's only so much you can do with Matlab uicontrols / uitable etc. You would get ultimate flexibility if you just resort to pure java solutions, e.g. wonderful swing-based JIDE Grids which are pre-packaged with each Matlab release. By the way, uitable is not much more than a trimmed-down version of Jide table in the first place. There's also a number of articles on using Jide within Matlab out there to get you started.

I have read about using VBA to concatenate terms together using VbCrLf; I personally used Ctrl-Enter to create a second line in the caption field in the properties box.
But, after I do my ctrl-enter, it then only shows the first line of my multi-line caption in the datasheet view of my form.
becomes this...
This form is meant to recreate the functionality our owner is looking for from a current excel spreadsheet (the ability to sort on various columns), so I can't just use a report.
Please tell me I'm missing something obvious such as a caption height property value or something. The multiline caption will be very useful to help maintain appropriate column widths for the data.
Whilst you can display multiple lines of content within the datasheet view for a table by increasing the row height of each record, e.g.:
A more appropriate solution might be to use a text box on a form to display the data, where the height of the text box can be predefined in the design of the form, and scroll bars can be displayed:
There is no solution to adjusting column headers in the specific "datasheet" form that I was trying to use. It's a nice quick way that works for 95% of your uses. But, if you need more control (like me and others on the internet) the only solution is to create the form as a "Tabular" form in the form wizard. There are other descriptions of this type of form in Access (just to be confusing).
This is also described as a continuous form likely because that's the form property value toggle when you dive into the details.
It's more work but you have full control over the size, format, etc. of your column headers when creating/designing a tabular form.
After installing R2018b, the first figure I opened contained an interesting message (shown in blue):
The reason it's interesting is because it contains features like text wrapping, transparency, the fact that the image maintains a constant width even though the text resizes (this reminded me of CSS3 flexbox, hence the tag), etc.
The last part of the animation is in slow motion, to better show how the div's size follows that of the figure.
In case it matters, I'm using Win 10 v1803.
Question:
I'd like to know how we can draw similar, custom, divs (for a lack of a better word) in our figures. (It's important to stress that this is not a UIFigure!)
What I found so far:
The Learn More link opens the page:
web(fullfile(docroot, 'matlab/creating_plots/interactively-explore-plotted-data.html'))
yet breakpoints in the entry points of either web or docroot (or even doc) aren't hit.
Assuming that this element is a Child of the figure, I attempted to locate a handle to it:
>> set(gcf,'MenuBar','none'); findall(gcf)
ans =
22×1 graphics array:
Figure (1)

AnnotationPane

however, making these controls invisible using set(h(2:end), 'Visible', false) didn't make the div disappear.
Saving the figure as .fig or generating code for it, doesn't leave any trace of this div.
When uiinspect-ing the figure, this div doesn't show (or at least, I couldn't find it).
I don't know what exactly I did to make it reappear once more, but since it's set to appear on the very first time you boot R2018b, I suspect deleting prefdir (obviously, after backing it up) and restarting MATLAB could bring it back.
The only thing I didn't try yet, is to attach a java debugger to MATLAB and attempt to trace the caller to com.mathworks.mlservices.MLHelpServices.setCurrentLocation (from mlservices.jar), which opens the help browser.
After some digging in the Java side of things (starting from findjobj, followed by a lot of .getComponent(0).getComponent(0)...), I've finally managed to locate the component in question. Here's what I learned:
This component is called InfoPanel, and is part of MATLAB's Java API. The class definition itself is found in:
MATLAB/R2018b/java/jar/hg.jar!/com/mathworks/hg/util/InfoPanel.class
To make it appear, we need to call the static method addBannerPanel, passing in a figure handle:
com.mathworks.hg.util.InfoPanel.addBannerPanel( figure(randi(1E4)) );
Or another signature that also accepts a custom panel:
jIP = com.mathworks.hg.util.InfoPanel;
jIP.setBackground(java.awt.Color(0.8, 0.7, 0.1));
com.mathworks.hg.util.InfoPanel.addBannerPanel( figure(randi(1E4)), jIP );
The MATLAB setting that controls whether this should appear is showinteractioninfobar inside the <prefdir>/matlab.settings XML.
It appears that the "interesting parts" of InfoPanel are private, which means it allows barely any customization (mostly some colors; not the string or the icon), but it should be fairly easy to make a copy of this class and expose all elements we need.
I have built a bokeh app that allows users to select windows in data and run python code to find and label (with markers) extreme values within these limits. For ease of interaction, I use the box select tool for the range selection. My problem arises when repeating this process for subsequent cases. After markers are placed for the results, they are rendered invisible by setting alpha to zero and another case needs to be chosen. When the new select box includes previous markers, they become visible based on the selection. How do I override this default behavior? Can markers be made unselectable? or can I add code to the customJS to hide them after they are selected?
Thanks in advance for any help!
There are a few possible approaches. If you just want non-selected glyphs to "disappear" visually, you can set a policy to do that as described here:
http://docs.bokeh.org/en/latest/docs/user_guide/styling.html#selected-and-unselected-glyphs
Basically, for bokeh.plotting, pass
nonselection_fill_alpha=0.0,
nonselection_line_alpha=0.0,
as arguments to your plot.circle call or whatever. Or if you are using the low level bokeh.models interface, something like:
renderer.nonselection_glyph = Circle(fill_alpha=0.0, line_alpha=0.0)
But be aware (I think you already are) that the invisible markers are still there, and still selectable if the user happens to draw a box over them with the selection tool.
If you truly want only a subset of the data to be visible and selectable after a selection, I'd say you want to replace the data in the column data source wholesale with the subset in your selection callback.
In my (programmatic) Matlab GUI, I have a listbox uicontrol.
What I want is to display checkboxes in front of each option. When a user clicks the checkbox, it's marked (and the element will be considered during the calculations later). While if the user clicks the label, a description of the selected option will be displayed in a text uicontrol to inform the user what the option means.
Basically, I want functionality similar to installation programs where you can select components to install and can get information about said components by clicking them (which does not necessarily mark them as selected).
Is there a way to do this with checkboxes or something similar?
There are actually 2 built-in controls that you could use within Matlab:
com.jidesoft.swing.CheckboxList
com.mathworks.mwswing.checkboxlist.CheckBoxList
Usage example (more details in my Matlab-Java book):
jList = java.util.ArrayList; % any java.util.List will be ok
jList.add(0,'First');
jList.add(1,'Second');
jList.add(2,'Third');
jList.add(3,'and last');
jCBList = com.mathworks.mwswing.checkboxlist.CheckBoxList(jList);
jScrollPane = com.mathworks.mwswing.MJScrollPane(jCBList);
[jhCBList,hContainer] = javacomponent(jScrollPane,[10,10,80,65],gcf);
set(jCBList, 'ValueChangedCallback', #myMatlabCallbackFcn);
jCBModel = jCBList.getCheckModel;
jCBModel.checkAll;
jCBModel.uncheckIndex(1);
jCBModel.uncheckIndex(3);
There's no "ready" way for doing that - as listboxes take only plain strings as entries.
You could "manually" draw checkbox fitted into the area of the listbox, but that might mean quite a lot of work to get everything working...
Another alternative is to go for a java-componenent - e.g. using the jide components available in matlab. See e.g.
http://undocumentedmatlab.com/blog/using-jide-combo-boxes/
for a few examples.
I'm using gxt 3.0.1 and I have Basic Grid added on my form.
Now I've added filter for each column which can be used over TextBox in menu of grid columns (basically it's Filter Grid now).
I have to make my own TextBox above grid and apply filter to it. And do that for each column of grid.
Filtering is done locally.
My idea was to look for code they made for their TextBox and apply it on mine TextBox.
But I failed.
It should be just String filter, which should work exactly as filter provided in Filter Grid.
Also I'm using UiBinder.
From the GridFilters javadoc
* Filtering is adjusted by the user using the grid's column header menu (this
* menu can be disabled through configuration). Through this menu users can
* configure, enable, and disable filters for each column.
This is meant to be used to configure column header menus to have filters built in, not set up text boxes outside of the grid - see http://www.sencha.com/examples/#ExamplePlace:filtergrid for how this is intended to work.
To build the way you are describing, start instead with making a StoreFilter object based on the contents of the TextBox, adding it to the store, and re-applying the filter each time the contents of the text box change.
Check out StoreFilterField for a working example, or follow the above instructions to build your own.
If this doesn't work, please provide a code sample in your question...
