more concise. Not only can we set the proxy for the table, but we can also set the proxy for the specified row or column.
void setitemdelegateforcolumn (int column, qabstractitemdelegate *delegate)//set agent void Setitemdelegateforrow for the column

If you use Ui->tablewidget->setitemdelegateforcolumn (3,new mytableitemdelegate) above. Then there is no need to judge the current column in the Createeditor function.

According to foreign media reports, although most users do not have touch screen devices, Windows 7 supports multi-touch. Therefore, if you purchase a touch screen device, Windows 7 users can use the multi-touch function. However, Linux users are not so lucky.
However, according to the Liliputing website, the ENAC computer Interaction lab ENAC Interactive Computing Laboratory has supported the multi-touch function in the Fedora12 system.
ENAC uses the X.org evdev driver to support hardware by

Hewlett-Packard has launched touchsmart tx2 rotating touch screen notebook. In early January, the company showed touchsmart TM2 in the CES International Consumer Electronics exhibition, foreign media have recently brought us out-of-the-box videos for this notebook.
Touchsmart series notebook rotating design allows users to change from a notebook to a touch screen tablet according to different needs. In terms of configuration, touchsmart TM2 does not

, may customize the input and output demand the characteristic, but its shortcoming is brings the computation quantity the rise and to the chip computation performance severe test. It is recommended to use the STM32F4 platform to drive the above camera. After testing, F407-driven ov2640 can easily reach 30 frames, plus the algorithm can reach 25~27 frame, basically meet the needs.
The 3 type of camera is dedicated to high-performance computing systems, such as the Raspberry Pie,

score. Based on the traditional greedy NMS algorithm, two kinds of improved functions are proposed and verified on two existing detection data sets. Through analysis, the accuracy of object detection can be improved effectively based on the detection frame overlap degree and the soft weight function of detection score. Future work can be considered from the perspective of learning more complex parameters or nonparametric equations. In addition, the end-to-end learning framework for object detec
