How to Develop a Calendar Widget.

That is not a simple challenge. You can look at the way the calendar widget is implemented for inspiration. You will have to do lots of rendering of your own. You can use any of the tree approaches Qt offers for that: rendering widgets with QPaintEvent, using QGraphicsView items or even using QML.

You can have a look at "qt-apps.org":http://qt-apps.org/content/show.php/running?content=91023 there are some implementations of calendars.

I'm sure there are more (perhaps in KDE, or some commercial solutions).

Using QML for UI will be much better I think, but then this will limit your application for 5th Edition devices and above only.

Hello Qtk,I want to interact with the dates

Did you look at the examples at qt-apps?
They have a full featured calender app, so they also handle clicks.
If you implement it with model/view and also have a custom view, you can handle clicks.

where is the problem?

On topic: I found that good calendar examples are hard to come by. I found a nice one (via a tip earlier in this forum, search the forum for calendar and you will find the topic), but that one I ended up getting send directly from the author. I have not seen it published in the open again yet.

The link I provided was one app at qt-apps. But if you find more, have a look at them, if they look like what yu need, look at the source.

I just recently create a minimal calendar in QtQuick in Javascript. It is unfinished, but shows dates correctly;)

If you have no existing code that works for you, start build it on your own. I have never seen a calendar build on buttons.

We can give you ideas, suggestions for specific technical stuff. But we don't write your code. If you want it with buttons, sit down, take QtCreator and start coding.

but gerolf i just need the correct direction,have u seen the calendar of nokia phones..it has that feature...

First: why do you think you need buttons? You can of course implement a calendar based on grid of buttons. I am just wondering how that would help you achieve your goals?

giesbert · wrote on 8 Apr 2011, 07:55

That you click on a button?
Or that you click on a date and something happens?

You can use a model/view (like Qt calendar widget) and react on the mouse events. No buttons needed. Qt has no build in "button calendar". and if you need one, build it. Or try if you can get the code for the nokia phone calendar.
