java - JPA orm.xml support for database index -


i not see option like, in orm.xml file, of jpa2.

<basic name="developer">     <index />     <column name="developer"/> </basic>

i see there hbm.xml files, offers that, wonder if jpa 2.0 lacks feature part of standard.

so can avoid transformation hbm.xml files...

jpa 2.0 table xsd type looks this:

<xsd:complextype name="table">     <xsd:sequence>         <xsd:element name="unique-constraint" type="orm:unique-constraint"                     minoccurs="0" maxoccurs="unbounded"/>     </xsd:sequence>     <xsd:attribute name="name" type="xsd:string"/>     <xsd:attribute name="catalog" type="xsd:string"/>     <xsd:attribute name="schema" type="xsd:string"/> </xsd:complextype>

while jpa 2.1 looks follows:

<xsd:complextype name="table">     <xsd:sequence>       <xsd:element name="unique-constraint" type="orm:unique-constraint"                     minoccurs="0" maxoccurs="unbounded"/>       <xsd:element name="index" type="orm:index"                     minoccurs="0" maxoccurs="unbounded"/>     </xsd:sequence>     <xsd:attribute name="name" type="xsd:string"/>     <xsd:attribute name="catalog" type="xsd:string"/>     <xsd:attribute name="schema" type="xsd:string"/> </xsd:complextype>

so, don't have index attribute on table type that's provided on per-entity level:

<entity class="post" access="field">     <table>         <index column-list="first_name,last_name" name="name_idx" unique="true"/>     </table>     <attributes>         ...     </attributes> </entity>

however, don't need use hbm2ddl in application. use flyway instead , way better off.

Image
i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
