This article mainly shows you how to achieve multi-form creation with Cpicket + Qt TabWidget, which is easy to understand and well-organized. I hope it can help you to solve your doubts. Here, let me lead you to study and learn how to achieve multi-form creation with Cpicket + Qt TabWidget.

Paging is usually accompanied in the development of form applications. TabWidget components combined with custom Dialog components can achieve a complex multi-form paging structure, which is also a common form layout scheme for ERP and other software.

First of all, to achieve a simple structure with only TabWidget paging, the following form layout, the blank part of the layout is a TabWidget component, below is a button, when the user clicks the button, automatically add the form to the TabWidget component.

The page association code is shown below, which automatically adds a form and sets the form's Tab to the specified IP address when the user clicks on_pushButton_clicked ().

T-> setTabIcon (cur,QIcon (": / image/1.ico"); ui- > tabWidget- > setCurrentIndex (cur); ui- > tabWidget- > setVisible (true);} / / execute void MainWindow::on_tabWidget_tabCloseRequested (int index) {if (indextabWidget- > widget (index); aForm- > close ()) when Tab is closed; void MainWindow::on_tabWidget_currentChanged (int index) {Q_UNUSED (index) is disabled by default on pages without Tab Bool en=ui- > tabWidget- > count () > 0; ui- > tabWidget- > setVisible (en);} each sub-form needs to dynamically obtain the parent form pointer to operate on itself according to the pointer. The sub-form code is as follows. # include "formdoc.h" # include "ui_formdoc.h" # include "mainwindow.h" # include # include FormDoc::FormDoc (QWidget * parent): QWidget (parent), ui (new Ui::FormDoc) {ui- > setupUi (this) QVBoxLayout * Layout = new QVBoxLayout (); Layout- > setContentsMargins; Layout- > setSpacing (2); this- > setLayout (Layout); MainWindow* parWind = (MainWindow*) parentWidget (); / / get parent window pointer QString ref = parWind- > GetTableNumber (); / / get selected tag index std::cout
