I've got a simple callback function when a button is clicked to remove the selected item from a listbox. It works correctly only if the topmost item is selected. Otherwise, it seems like the item directly above the actual selection gets removed rom the LB. Here's the callback:
Function Callback_RemoveSite
LogEx::Write " RemoveSite button clicked. Inside callback function."
${NSD_LB_GetSelection} $Listbox_SiteNameID $0
${NSD_LB_DelString} $Listbox_SiteNameID $0
FunctionEnd
And here is the snippet of the dialog/page where it's potentially called:
${NSD_CreateListBox} 0u 30u 150u 90u
Pop $Listbox_SiteNameID
${NSD_CreateButton} 172u 105u 58u 12u "--> Remove Site"
Pop $Button_RemoveSite
${NSD_OnClick} $Button_RemoveSite Callback_RemoveSite
I'm not a GUI expert, but am I missing somthing here?
