I wanted to do some operations after QTableWidget click, but now found that don't really get the click event, my code is written so: in the constructor connect (UI) tableWidget, SIGNAL (itemClicked (QTableWidgetItem *)), and this, SLOT (testSlot (QTableWidgetItem))); The corresponding slot function void Table_RC: : testSlot (QTableWidgetItem * item) {UI. PushButton - & gt; SetText (" BBB "); } then find no reaction, when you click is excuse me why? Thank you very much!

Don't see where there's a problem ~ ~ ~ the UI has been setup successfully DoubleClicked also tried I also particularly curious why not try void itemSelectionChanged () when the signal is ok

Fixed form inside when the content of the item is empty itemClicked not is, must be value the item can be but I still is not very good although the item's text is empty but * item should signal not how ah

Reference 3 floor bahuasheng in 2010-03-28 published the preserving: fixed form inside when the content of the item is empty itemClicked no is, must be value the item can be but I still is not very good although the item's text is empty but * item should signal not ah how can your initial form is empty? Because with similar tableWidget - & gt; SetItem (0, 0, new QTableWidgetItem (" XXX ")); Only the Item, otherwise there is no really,

Refer to the fifth floor yangfanxing in 2010-03-28 published 11: your initial form is empty? Because with similar tableWidget - & gt; SetItem (0, 0, new QTableWidgetItem (" XXX ")); . Form is literally dragged N rows of N columns of just the content inside is empty set to edit and doesn't work I tried

CodePudding user response:

Well, and summarizes the above post, if the Item is empty, no access to the event message, do not know whether so,,, should be,

CodePudding user response:

Item have value and editing, will trigger the itemclicked events;
The item value but editable, not trigger this itemclicked event,
