% First, create the search-box component on the EDT, complete with invokable Matlab callbacks:
jSearch = com.mathworks.widgets.SearchTextField('Symbol'); % 'Symbol' is my default search prompt
jSearchPanel = javaObjectEDT(jSearch.getComponent); % this is a com.mathworks.mwswing.MJPanel object
jSearchPanel = handle(jSearchPanel, 'CallbackProperties'); % enable Matlab callbacks % Now, set a fixed size for this component so that it does not resize when the figure resizes:
jSize = java.awt.Dimension(100,25); % 100px wide, 25px tall
jSearchPanel.setMaximumSize(jSize)
jSearchPanel.setMinimumSize(jSize)
jSearchPanel.setPreferredSize(jSize)
jSearchPanel.setSize(jSize) % Now, attach the Matlab callback function to search box events (key-clicks, Enter, and icon clicks):
jSearchBox = handle(javaObjectEDT(jSearchPanel.getComponent(0)), 'CallbackProperties');
set(jSearchBox, 'ActionPerformedCallback', {@searchSymbol,hFig,jSearchBox})
set(jSearchBox, 'KeyPressedCallback', {@searchSymbol,hFig,jSearchBox}) jClearButton = handle(javaObjectEDT(jSearchPanel.getComponent(1)), 'CallbackProperties');
set(jClearButton, 'ActionPerformedCallback', {@searchSymbol,hFig,jSearchBox}) % Now, get the handle for the figure's toolbar:
hToolbar = findall(hFig,'tag','FigureToolBar');
jToolbar = get(get(hToolbar,'JavaContainer'),'ComponentPeer'); % or: hToolbar.JavaContainer.getComponentPeer % Now, justify the search-box to the right of the toolbar using an invisible filler control
% (first add the filler control to the toolbar, then the search-box control):
jFiller = javax.swing.Box.createHorizontalGlue; % this is a javax.swing.Box$Filler object
jToolbar.add(jFiller, jToolbar.getComponentCount);
jToolbar.add(jSearchPanel, jToolbar.getComponentCount); % Finally, refresh the toolbar so that the new control is displayed:
jToolbar.revalidate
