i have section , formtoolkit in 1 composite. when enter text in search box (text field) should filter based on user input , show results below. facing 1 problem while filtering data. how refresh data in composite when user enters text in text field.
i want solution same how works in
preferences -> compiler -> errors/warnings?
example:
if enter "null" in search box display related "null" values below.
how achieve implementation filtering/refreshing composite data?
the preference page reference composite containing controls filtered. composite uses gridlayout layout.
each control has griddata layout data. set control visible or invisible uses:
control.setvisible(visible); ((griddata)control.getlayoutdata()).exclude = !visible; once has been done calls:
composite.layout(true, true); to redo layout of composite completely.
most of code in org.eclipse.jdt.internal.ui.preference.optionsconfigurationblock
to filtering create text field filter , add modifylistener listen changes in text.
each time text changes match text of each control filter , set control visible / invisible described above. @ end of filtering layout call.
