gtkmm中的文字換行GtkTreeView

Question

我在Linux中使用gtkmm-2.4 GUI軟件包編寫程序。如何設置TreeView對象的文本列來執行C++中的文字換行？

Answer 1

啊，GTK的CellRenderers奇怪而令人愉快的話。

#include <pangomm/layout.h> 

// say we want to wrap the 3rd column in our treeview 
int colNum = 3; 
Gtk::CellRendererText* pCellRendererText = dynamic_cast<Gtk::CellRendererText*>(pTreeView->get_column_cell_renderer(colNum)); 
pCellRendererText->property_wrap_mode() = Pango::WRAP_WORD; 
pCellRendererText->property_wrap_width() = 20;
