[SOLVED] Buttons doesn't "activate"
-
Hi,
I'm a beginning programmer and new to Qt , so the question might be stupid, but i follow the youtube tutorials from user "rootshell" and when i deploy any widget at mainwindow.ui it is enabled but it isn't "activated" in a sense that i can't click it (e.g. can't check the checkbox or radio button). The only way i can do that is when i use grabMouse (or e.g. grabKeyboard) function but when i try to use the same function on various buttons (e.g. grabMouse on radioButton and on radioButton_2) only the last one works (the others can't be checked). What's the problem here?
I should add that in the properties window field "enabled" is checked, and when i additionally use setEnabled(true) function on buttons nothing changes... any help?
P.S. I use Qt Creator 2.7.0Regards

Hi and welcome to devnet,
What OS are you on ? What version of Qt ?
Do you have a minimal example of your code that doesn't do what you want ?

Hi,
i work on windows 7, Qt Creator 2.7.0 based on Qt 5.0.2 (32bit).
mainwindow.cpp
@#include "mainwindow.h"
#include "ui_mainwindow.h"MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
ui->pushButton->grabMouse();
ui->pushButton->setText("close");
connect(ui->horizontalSlider,SIGNAL(valueChanged(int)),
ui->progressBar,SLOT(setValue(int)));
ui->horizontalSlider->grabKeyboard();
ui->radioButton->setEnabled(true);
ui->radioButton_2->setEnabled(true);
}MainWindow::~MainWindow()
{
delete ui;
}

in this case Push button does work (because i used grabMouse function) and slider reacts only for keyboard arrows, doesn't react for mouse. radio buttons doesn't do anything (doesn't "check" themselves). Also when i add grabMouse on radioButtons only the last assigned button works (e.g radioButton_2 does work, and push button and radioButton don't)
Here's my window:

Removing the two grab functions:
What do you expect from your close button ?
Do you expect your slider to move using your keyboard before giving it focus with the mouse ? Which key are you using ? -
grabMouse and grabKeyboard should only be used in specific conditions. Most of the time you won't need them at all.
You're welcome !
