JAssetComponent.getComponent(0).setMaximumSize(jSize) % Expand the SearchTextField component to max available width Setappdata(hContainer,'jAssetChooser',jAssetChooser) = javacomponent(jAssetComponent,hContainer) JAssetComponent = jAssetChooser.getComponent
% Create a SearchTextField control on top of the combo-box Set(hContainer1, 'Units','pixels', 'Position',) For example, we can use Matlab’s internal widget:
These two functionalities are often correlated, and today’s article will discuss both.īefore I dive into details of the implementation I ended up with, note that there are simpler alternatives. Auto-completion is usually reserved for the case of the user-entered text being automatically completed as they type, whereas auto-winnowing only updates the drop-down options on-the-fly. The correct term should actually be “auto-winnowing” or “auto-filtering”. Note that in this particular case, I use the term “auto-completion” loosely. Interactive Matlab auto-completion widget The idea was for Matlab to automatically auto-complete the financial instruments matching the entered text, as it is being typed, similarly to other standard auto-completion widgets (e.g., Google’s search box), including the use of wildcards and regular expressions: The idea was simple enough: the user selects a class of financial assets from a drop-down, then one or more actual financial securities from a dynamically-populated drop-down (based on the asset class), then the date range and analysis function, and finally the results are plotted in the main panel. Such a case happened to me, when a consulting client asked me to integrate an auto-completion widget in a GUI that I designed for them. Do you ever get a feeling when designing a Matlab GUI, that existing components/controls are simply not enough to achieve the desired functionality/appearance?
