QComboBox with QSqlQueryModel

[jpn]

I didn't do anything special. I have the ui with QComboBox with SizeAdjustPolicy set to adjustToContents (not on first show)

modelCategories = new QSqlQueryModel;
...
// connecting to PostgreSQL database
...
modelCategories->setQuery("SELECT category_name FROM mytable");
comboBox->setModel(modelCategories);

modelCategories = new QSqlQueryModel;
...
// connecting to PostgreSQL database
...
modelCategories->setQuery("SELECT category_name FROM mytable");
comboBox->setModel(modelCategories);

To copy to clipboard, switch view to plain text mode 

There's not much I can do with that piece of code. I wanted to test and see myself, that's why I asked for something compilable to test with.

I took one of the SQL examples shipped with Qt and modified it to use combo boxes instead of tables. The attached example seems to work pretty fine for me. Does it work for you?
