Loading indicator for QX11EmbedContainer

guilherme last edited by

There was a need to display the preloader while in the container. QX11EmbedContainer I don't see it. There's a moment to start displaying the pre-loader, on the signal. clientIsEmbedded() I can determine the moment of the intrusion and stop showing the proloader, and also stop showing in case of error. But the question arose - what means would it be better to display the preloader himself? If I understand correctly, QSplashScreen It doesn't work, because it's tied to the view. QProgressBar - it is unclear how to set the percentage of the operation. Show me. *.gif as at QMovie?

If there is no need to determine the percentage of the operation, an image can be easily displayed. As an example:
```
m_pProgressText = new QLabel("Загрузка...", this);
m_pProgressImage = new QLabel(this);
QMovie* movie = new QMovie(":/icon/throbber.gif");
m_pProgressImage->setMovie(movie);
movie->start();
```
At the same time, when the application is moved to Windows, there must be a library of qgif4.dll, otherwise the image will not be displayed.

In short, I understand, under the sorcium, you mean that two Louders are trying to sleep two chunks in the same place, like the two variables are recorded in the same box.It follows that there should be a manager of the louders who organizes, which may be Map or not. Algorithm Spaven's chunk at the boat:(1) void RollChankFromSpawn() The boater chooses to spawn from the chunk.(2) Choose a condidate from the empty coordinates nearby (let 10x7)(3) void PrepareSpawnOnTile(Vector2 tile, bool checkEmpty) Collects an infu about the neighbors, 9x7 already know, but others can be stored in the chanque.(4) Two more "births" (11x7 and 10x8) that can be part of other chunkos, so we're asking the manager for the lotters. ChunkLoader HasChunkOnTile(Vector2 pos) Give a boat with a chanc on that coordinate for both of us.5a) If both responses from the manager null, void SpawnChunkOnTile(Vector2 tile)♪5b) If not, we tell the manager to unite the boats. void ConnectLoadersAndSpawnChunkOnTile(ChunkLoader[] loaders, Vector2 tile)♪ The lottery itself, which wanted to spawn and the rest of the non-repetition louders in the empty positions (may be up to 4), and where we're going to jump right from paragraph (3), without (4), after the detachment (ation of one boat, lists of chunks and QuadLists of the others). It'll solve the problem of finding ways.

This happens because you call the test() function in an expression like this:{{ prueba() }} This function will be called at least twice if you use expressions like that.The reason is that Angular executes summary cycle until everything is updated (so it will be at least twice). In your case, you will run the first time to return the value and the second time to check if any changes remain.Calling a function that way is not a good practice.

line In the context of this code, it's a set of 10 lines, i.e. the symbols. char); in order to reduce confusion, I will call these index numbers. As I understood your code, you'd like to play a role. read change that point in the mass line♪ But your code changes only the variable value. p inside the function and the body itself. line As a result, it remains uninitiated. To change the meaning in the body itself. line, you need to transmit the index to the value (i.e. the indicator to the index) and to change the meaning of the index. The code below is:#include <stdio.h> char string[100]; int i = 0; void read(char *p){ / Меняем значение не в переменной внутри функции, / / а в том месте, куда указывает указатель */ *p = &string[i]; while((string[i] = getchar()) != '\n') i++; string[i++] = '\0'; } int main(){ char *line[3]; int i; for(i = 0; i < 3; i++) read(&line[i]); /* Передаём указатель на значение массива */ for(i = 0; i < 3; i++) printf("%s\n", line[i]); return 0; } In addition to this, there are other issues in the code: string Incorporates only 100 symbols, thus attempting to read more than 100 symbols can lead to vague behaviour, particularly the collapse. And you've got code blocks badly decorated, which can complicate the reader. But it's not a question, and I hope you understand it yourself.

I have a few options:Option number 1 if you don't need all the tables You can try to list what you can. use (*). Option #2, as Yura Ivanov said, Insert a index on the Type Field (NE) PRIMARY, a index) should be given faster processing. There's a phpmyadmin in there. There's a "index" button in the deposit.
