用Java技巧在Matlab中制作自动完成搜索框
我是matlab新手，我想制作一个自动完成搜索框，嵌入到gui中。 我一直在网上寻找，我发现：，这正是我想要做的 但我有两个问题： 1我无法从组合框下拉面板或通过在搜索文本框中键入来选择单词 2如果与列表不匹配，我无法更改单词的背景颜色 我正在使用Matlab2016a 代码如下：用Java技巧在Matlab中制作自动完成搜索框,java,matlab,swing,Java,Matlab,Swing,我是matlab新手，我想制作一个自动完成搜索框，嵌入到gui中。 我一直在网上寻找，我发现：，这正是我想要做的 但我有两个问题： 1我无法从组合框下拉面板或通过在搜索文本框中键入来选择单词 2如果与列表不匹配，我无法更改单词的背景颜色 我正在使用Matlab2016a 代码如下： function PPP() % function for built the GUI position = [10,100,90,20]; hContainer = gcf; % combobox
function PPP()
% function for built the GUI

options = {'a','b','c','cippo','pippo','lure','azurra','che','cosa','stai','scriviunacosalunghissima'};
model = javax.swing.DefaultComboBoxModel(options);
jCombo = javacomponent('javax.swing.JComboBox', position, hContainer);
jCombo.setModel(model);
jCombo.setEditable(true);
% Create the SearchTextField (after the hidden combo was created)
jAssetChooser = com.mathworks.widgets.SearchTextField('Enter search:');
jAssetComponent = jAssetChooser.getComponent;
javacomponent(jAssetComponent,position,hContainer);
% Set callbacks
hjSearchButton = handle(jAssetComponent.getComponent(1), 'CallbackProperties');
set(hjSearchButton, 'MouseClickedCallback', {@updateSearch,jCombo,jAssetChooser});
hjSearchField = handle(jAssetComponent.getComponent(0), 'CallbackProperties');
set(hjSearchField, 'KeyPressedCallback', {@updateSearch,jCombo,jAssetChooser});
jComboField = handle(jCombo.getComponent(2), 'CallbackProperties');
set(jComboField, 'KeyPressedCallback', {@updateSearch,jCombo,[]});
In this way i should be able to select an item either from the combo-boxs dropdown panel, or by typing in the search text-box.
