Saya ingin bertanya kepada semua, saya ingin mengklik butang di tetingkap utama untuk memanggil tetingkap baharu Tetingkap ini ialah tablewidget pada masa ini, tetingkap timbul boleh dilaksanakan, tetapi jadual tidak boleh dipaparkan dan ada hanya tingkap kosong. Saya benar-benar tidak dapat mencari sebab, tolong beri saya nasihat.
Ini adalah kod tetingkap utama
