Method for displaying textbox in navigation system and navigation system

Abstract

The invention discloses a method for displaying a textbox in a navigation system and the navigation system. The method for displaying the textbox comprises the following steps of: firstly, acquiring and calculating the word count of a text to be displayed of the textbox; secondly, determining the length of the textbox according to the acquired word count; and thirdly, dynamically generating the textbox, and displaying the textbox namely the text. The method for displaying the textbox in the navigation system can determine the length of the textbox according to the word count of the text to be displayed and dynamically generate the textbox, so the method not only can well display the content of the text of the textbox but also cannot cause the problem that the blank part in the textbox can occupy more space of a display screen of a navigation device due to the oversize textbox when the text is short, the display effect is good, and the user can use smoothly and conveniently.

Description

technical field [0001] The invention relates to the field of GPS navigation, more specifically, to a text box display method in a navigation system and the navigation system. Background technique [0002] At present, the global positioning system (Global Positioning System, GPS) for vehicles is one of the important application directions of GPS navigation. The GPS antenna of the car GPS navigation system receives the data information transmitted by at least 3 of the 24 GPS satellites around the earth, combined with the electronic map stored in the car navigation terminal, the position coordinates determined by the GPS satellite signal and this match to determine the exact position of the navigation object in the electronic map. The user driving the vehicle can select the driving route by the navigation system when driving, and set the starting point, destination, necessary places, avoidance places, etc. in the navigation system. The navigation system plans an appropriate ro...

Problems solved by technology

When the navigation system displays the text boxes, the specifications of these text boxes are fixed, that is to say, the size of the text box body is uniform, and because the length of the road name and the name of the information point is different, In order to better display longer road names or information point names, the length of the text box should not be too short; however, in actual use, there are often some roads or information point names that are shorter, and the navigation device still uses the system The set text box displays the road name, and the road name only occupies a small part of the text box, but the text box occupies a large part of the display screen of the navigation device, which becomes a waste and affects the user's ability to see clearly in a wider range The electronic map displayed on the display screen of the navigation device

[0019] In order to solve this problem, there is a method of setting the background color of the text box to be transparent in the existing system, so that the larger text box will not prevent the user from seeing the text displayed on the display screen of the navigation device in the part where the text is not displayed. Electronic map, but this causes the display of the text part of the text box to be affected, the text content cannot be displayed well, and it hinders the user from reading the text
