 Posted: Sat Aug 10, 2024 7:31 am Post subject: Extending Context Menu of Data Dissect Structure Entry |
 |
|
Hi all,
I am seeking LUA expert support to extend the Context Menu that appears when you right-click on an entry in the Data Dissect Window.
Here's the pseudo-code I am thinking about - if that makes any sense 
| Code: |
// The means to register the menu item and register a function to invoke
MyRightMenuItem ("Section Name", "Get entry info...", &GetEntryInfo())
// The function to register
GetEntryInfo()
{
if IsValid(address) HandleValidEntry(); // We check if all is good and do something about it
else HandleInValidEntry(); // We log it, pop an error or something
}
|
I have really no clue how to get this done - if, at all, possible.
Thank you!

Just an example targeting adding a right click menu to the relevant section.
I hope you have the codes you will use in the click ready.
| Code: | function popupblaclick1(sender)
showMessage('Menu 1 was clicked')
end
function popupblaclick2(sender)
showMessage('Menu 2 was clicked')
end
-----------------------------------------------
local exFrm1 = ""
function addPPMn11()
for i=0,getFormCount()-1 do
local formClassName = getForm(i).ClassName
if formClassName=='TfrmStructures2' then
aa4 = getForm(i).pmStructureView
exFrm1 = getForm(i)
pmenu_items=menu_getItems(aa4)
if mi1 then mi1.Destroy() end
mi1=createMenuItem(aa4)
menuItem_setCaption(mi1,'Menu i1')
menuItem_onClick(mi1,popupblaclick1)
menuItem_add(pmenu_items, mi1)
if mi2 then mi2.Destroy() end
mi2=createMenuItem(aa4)
menuItem_setCaption(mi2,'Menu i2')
menuItem_onClick(mi2,popupblaclick2)
menuItem_add(pmenu_items, mi2)
end
end
end
registerFormAddNotification(function(exFrm1)
local t=createTimer()
t.Interval = 1
t.OnTimer = function (timer)
timer.destroy()
addPPMn11()
end
end) |

Thank you both!

I added an [ENABLE] and a [DISABLE] section, assigned to Cheat Table.
I enable it, and it appears to be doing nothing - at least, there are no new menu items appearing in the popup.
Am I using it wrong?
Thanks!
Edit
Managed to fix it.
Next question is, how do I get the value right-clicked from the sender - so I can do something with it...
Final code (for posterity):
| Code: | [ENABLE]
{$lua}
function getFormStructureDissect()
for k,v in ipairs(enumStructureForms()) do if v.ClassName=="TfrmStructures2" then return v end end
return nil
end
function popupLookupNameIDClick(sender)
showMessage('popupLookupNameIDClick!')
end
local frmDissect
function fn_AddPopupMenuItems()
if miNameIDLookup then miNameIDLookup.destroy() end
frmDissect=getFormStructureDissect()
if frmDissect~=nil then
local pmDissect = frmDissect.pmStructureView -- pmDissect = TfrmStructures2.PopupMenu
local mnItemDissect=pmDissect.getItems() -- mnItemDissect = main MenuItem of TfrmStructures2.PopupMenu
miNameIDLookup=createMenuItem(pmDissect)
miNameIDLookup.setCaption('Find Name from ID')
miNameIDLookup.setOnClick(popupLookupNameIDClick)
mnItemDissect.Add(miNameIDLookup)
end
end
local function pmRegTimer_tick(thisTimer) ---- Timer callback
thisTimer.Active = false
fn_AddPopupMenuItems()
print('Registered popupLookupNameIDClick.')
thisTimer.destroy()
thisTimer=nil
end
objPopupMenuNotification= registerFormAddNotification(function(frmDissect)
local t=createTimer(getMainForm())
t.Interval = 200
t.OnTimer = pmRegTimer_tick
end
end)
[DISABLE]
{$lua}
if syntaxcheck then return end
unregisterFormAddNotification(objPopupMenuNotification)
if miNameIDLookup then
miNameIDLookup.destroy()
print('Destroyed popupLookupNameIDClick.')
end

Okay, this works for the most part - however, the popup menu item keeps disappearing.
For example, when I add a new column, the popup menu item disappears.

Save this as a Lua file within the autorun directory. It will add the respective item to the popupmenu of the Structure Dissect form. The function attached to that particular object returns the index of the menu item.
| Code: |
local function addItemToPopupMenu(form)
if form.findComponentByName('miNameIDLookup') then miNameIDLookup.destroy(); miNameIDLookup = nil end
local miNameIDLookup = createMenuItem(form.pmStructureView)
local miSep = createMenuItem(form.pmStructureview)
miSep.Name = 'miNewSep1'
miSep.Caption = '-'
form.pmStructureView.Items.add(miSep)
miNameIDLookup.Name = 'miNameIDLookup'
miNameIDLookup.Caption = 'Find Name from ID'
miNameIDLookup.OnClick = function (sender)
print('popupLookupNameIDClick! with index: ' .. sender.MenuIndex)
end
form.pmStructureView.Items.add(miNameIDLookup)
end
local function formCreateNotify(form)
if form.ClassName ~= 'TfrmStructures2' then return end
local timer = createTimer(MainForm)
timer.Interval = 15
timer.OnTimer = function(t)
addItemToPopupMenu(form)
t.destroy()
end
end
registerFormAddNotification(formCreateNotify)

It would appear new windows do not get the new popup menu item.
How would I make it so that the popup menu is registered for each dissect window that is opened?
Thank you!

registerFormAddNotification should have done that

For some reason, it's the first dissect window only.
| Code: | objPopupMenuNotification=registerFormAddNotification(function(frmDissect)
local t=createTimer(getMainForm())
t.Interval = 200
t.OnTimer = pmRegTimer_tick
end)

How does pmRegTimer_tick get the frmDissect parameter passed to the callback?

| Code: |
local frmDissect => this is a global in scope of the script (I think :D)
local function pmRegTimer_tick(thisTimer) ---- Timer callback
thisTimer.Active = false
fn_AddPopupMenuItems()
--print('Registered popupLookupNameIDClick.')
thisTimer.destroy()
thisTimer=nil
end

you do need to assign the parameter given to the function to that local var though. And since they have the same name that's going to be problematic
change objPopupMenuNotification=registerFormAddNotification(function(frmDissect) to objPopupMenuNotification=registerFormAddNotification(function(newfrmDissect)
and then in the function assign do a frmDissect=newfrmDissect

Thank you!
No luck though - the new popup menuitems are still missing in a new window
| Code: | objPopupMenuNotification=registerFormAddNotification(function(newfrmDissect)
frmDissect=newfrmDissect
local t=createTimer(getMainForm())
t.Interval = 200
t.OnTimer = pmRegTimer_tick
end)

registerFormAddNotification gets called for every form. Check the class name
| Code: | function forEachAndFutureForm(classname, func)
local i
for i=0,getFormCount()-1 do
local f = getForm(i)
if f.ClassName==classname then
func(f)
end
end
registerFormAddNotification(function(f)
if classname==f.ClassName then
f.registerFirstShowCallback(func)
end
end)
end
forEachAndFutureForm('TfrmStructures2',function(f)
local mi = createMenuItem(f.pmStructureView)
mi.Name = 'miHelloWorld'
mi.Caption = 'Hello'
mi.OnClick = function() print'Hello' end
f.pmStructureView.Items.add(mi)
end) |

I'll say, okay and admit I am not sure what am I looking at.
Is this something I should be building into my code or it this built into CE?
I am not very good with LUA - thank you for your patience!
