I am developing a QGIS plugin, using python and Plugin Builder plugin of QGIS. I have created a textEdit text box on the plugin. I want to show a list of matching words from the database as user will type in the textEdit and words will be shown in drop down as google and any other search engine provides.
Basically I want to build a search engine. It's like I want to use 'LIKE' operator and based on that I want to show matching results in drop down in the plugin. How is it possible in QGIS plugin. What event I have to use with the textEdit to list down the search. If there is any other open source plugin with same functionality available that would also be helpful.
