displaying Text in QTAble dynamically

[raghvendramisra]

hi,
i have an application in which i have to read the file and display the data in a table.
I am using setText() function to display the text.

now my problem is that the text is displayed in the table only after file has reached the end i.e i am getting only the last data in the table.
but i want to view data dynamically i.e the table cell should show all the data read from the file.

how can i do this???????????

What values do you pass to QTable::setText()?

[raghvendramisra]

well i pass QString as setText() only take QString as the argument

Would you mind showing the relevant piece of code, where you read a file and fill the table?

ya! the code below is from the section where i am reading the binary file and displaying it in the table cell.
but i am able to see only the last msg.

///////////////////////

unsigned int uiData;
QString szTmp;

fp = fopen("test.bin","r+b"); //test.bin is the binary file containing data in the form of structure MNTPACK
fseek( fp, 0L, SEEK_SET);


while(1)
{

fread(pMtStruct,sizeof(MNTPACK), 1, fp); //pMtStruct is a pointer to MNTPACK struct

if(!feof(fp))
{

uiData=pMtStruct->DataPack; //DataPack is an unsigned integer Value

szTmp = szTmp.setNum(uiData,16);
table1->setText(1,1,szTmp);
table1->updateCell(1,1);
}
else
{

break;
}

}

[jpn]

table1->setText(1,1,szTmp);

table1->setText(1,1,szTmp);

To copy to clipboard, switch view to plain text mode 

This sets text to same cell (1,1) every time. You might also want to consider using QFile for more convenient file handling..

actually thats what the problem is!!!!!!!!!!!!!
I wanted to write the data in the same cell and view it as it changes.
but instead i am able to view only the last data from the file.
hope you got the problem???????

First of all, you would have to let the application to process its events every once in a while to let it actually receive necessary paint events and so on. You could try calling qApp->processEvents() after each setText() to make it happen. However, that might still be a bit too fast for one actually to see the changes, so you might have to change the approach a bit (delayed changes?).

Thanx ,
i tried this by using thread and it is working well

But now the problem is that in QTable i am displaying the contents read from file as QString. Now if i read a pure numerical value , it is displayed at the right End of the cell but a string is displayed at the left End of the cell. so this looks very auckward.

How can i display the contents at one location only in a cell

Thanks
