How to detect when something is pasted into an edit control?

[N_athan]

Using a tool to read window messages i noted that whenever i past something in an edit control with (ctrl v) on a AutoHotkey GUI
it receives a message of wm_paste, is possible somehow to detect when this happens?

According to the documentation of the AutoHotkey OnMessage() function, it depends on whether the message is sent or posted to the control:

Code: Select all

Messages sent to a control (rather than being posted) are not monitored because
the system routes them directly to the control behind the scenes. This is seldom
an issue for system-generated messages because most of them are posted.

If the message is posted, then OnMessage() should be able to notify your code of the message arrival.

Code: Select all

Gui, Font, s10
Gui, Add, Edit, w250
Gui, Show

#If WinActive("ahk_class AutoHotkeyGUI") && guiClassNN("Edit")
~^v::MsgBox, 64, Pasted text, %Clipboard%
#If

guiClassNN(str := "") {
 GuiControlGet, classNN, Focus
 Return str > "" ? Instr(classNN, str) : classNN
}

Good idea (and script), @mikeyww, but what if a paste occurs via Right-click + Paste?

Different question, different script, but I'm not sure of the script.

Different question ...

Quite right, missed that detail in the question.
