popupmenu

I've made a pop-up menu with one menu item, I want to enable it only when I do a right click on a tree item of a certain class type otherwise disable it. How can I achieve this?

Attached the xml files. item_list.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android

I want a popup menu above a button: Delphi wraps the Win32 menu system in a way that seems to preclude every mode or flag that the underlying Win32 API provides that was not in the VCL author's brain on that day. One such example appears to be the TPM_BOTTOMALIGN which can be passed into TrackPopupMenu but, the Delphi wrapper appears to render this not only impossible in the stock VCL, but by injudicious use of private and protected methods, is impossible (at least seems to me to be impossible) to do either accurately at runtime, or by overrides. The VCL component TPopupMenu is not very well
